The Anaimangalam Copper Plates are a set of royal charters issued by Chola kings in the early 11th century CE, formalising a land grant in favour of a Buddhist monastery in Nagapattinam, Tamil Nadu. They are widely considered the most important surviving epigraphic records of the Chola Empire held outside India.
They are known by two principal names: Anaimangalam Plates (after the village whose lands were granted) and the Leiden Plates (after Leiden University in the Netherlands, where they were preserved for over 160 years).
| Parameter | Detail |
|---|---|
| Official Name | Anaimangalam Copper Plates (also: Leiden Plates) |
| Named After | Village of Anaimangalam, near Nagapattinam, Tamil Nadu |
| European Name | Leiden Plates (after Leiden University, Netherlands) |
| Type | Royal Copper Plate Land Grant (Tamrapattra / Copper Pattra) |
| Issuing Dynasty | Imperial Chola Dynasty |
| Period | Issued in regnal year 21 of Rajaraja Chola I (c. 1005–1006 CE) |
| Inscribed By | Rajendra Chola I (formalised in copper by son, to permanently preserve father's oral decree) |
| Languages | Sanskrit (Grantha script) + Tamil |
| Physical Composition | 21 large copper sheets + 3 smaller plates |
| Total Weight | ~30 kilograms |
| Binding | Circular copper ring bearing the royal Chola seal (Tiger emblem) |
| Location (Before 2026) | Leiden University Library, Netherlands (since 1862) |
| Returned To India | 15–16 May 2026 (PM Modi's visit to Netherlands) |
The copper ring binding the plates is engraved with the Chola Tiger Emblem — the royal seal of Rajendra Chola I. The tiger, along with two fish and a bow, is the iconic symbol of the Chola dynasty.
UPSC may ask: "The Leiden Plates / Anaimangalam Copper Plates are associated with which dynasty?" → Chola Dynasty. They may also test the two-name confusion: Leiden = European name; Anaimangalam = Indian name. Both refer to the same artefact.
| Type | What It Records | Famous Example |
|---|---|---|
| Land Grant (Dana Patra) | Gift of village/land to temples, monasteries, or brahmanas; includes tax exemptions | Anaimangalam Plates (Chola) |
| Genealogical Records | Royal lineage, titles, conquests of the issuing king | Tiruvalangadu Plates (Rajendra Chola I) |
| Administrative Orders | Rules for village governance, irrigation duties, tax collection | Uttarameruru Inscription (Parantaka Chola) |
| Military/Victory Records | Battle victories, tribute received from subordinate kings | Kalingattuparani (Kulottunga I era) |
The Imperial Chola Dynasty (850–1279 CE) was one of the longest-ruling and most powerful dynasties in South Indian history. Founded when Vijayalaya Chola captured Thanjavur (~850 CE), the dynasty reached its zenith under Rajaraja Chola I and his son Rajendra Chola I in the 10th–11th centuries.
The Chola heartland was the Kaveri River delta in present-day Tamil Nadu. At their peak, the empire unified peninsular India south of the Tungabhadra River, and their naval power extended to Sri Lanka, Maldives, and Southeast Asia (Srivijaya).
| Ruler | Reign | Key Contributions | Link to Plates |
|---|---|---|---|
| Rajaraja Chola I (born Arulmozhi Varman) | 985–1014 CE | Built Brihadisvara Temple, Thanjavur (UNESCO WHS); conquered Sri Lanka, Maldives, Malabar Coast; patronised Chudamanivarma Vihara | Issued original oral grant in regnal year 21 (c. 1005–06 CE) |
| Rajendra Chola I | 1014–1044 CE | Gangaikonda expedition; founded Gangaikonda Cholapuram; naval raid on Srivijaya (1025 CE); title: Gangaikondacholan | Inscribed grant onto copper plates to make it permanent |
| Temple | Built By | Location | Key Feature |
|---|---|---|---|
| Brihadisvara (Rajarajesvara) Temple | Rajaraja Chola I (1003–1010 CE) | Thanjavur, Tamil Nadu | 66-metre vimana; dedicated to Lord Shiva; Chola murals |
| Gangaikonda Cholapuram Temple | Rajendra Chola I (~1025–1035 CE) | Ariyalur dist., Tamil Nadu | Built to commemorate Gangaikonda (Ganges) expedition |
| Airavatesvara Temple | Rajaraja Chola II (12th century) | Darasuram, Kumbakonam | Chariot-shaped structure; intricate Dravidian carvings |
Rajaraja Chola I's birth name was Arulmozhi Varman — the protagonist of the Tamil novel Ponniyin Selvan by Kalki (1950). The novel explicitly mentions the Leiden Plates, making the artefact well-known in Tamil popular culture.
The Anaimangalam Copper Plates are royal charters formalising the donation of the village of Anaimangalam (near Nagapattinam, Tamil Nadu) and its surrounding lands — along with land revenues, tax arrangements, and irrigation duties — to the Chulamanivarma Vihara (also spelled Chudamani Vihara), a Buddhist monastery at Nagapattinam.
The monastery was built by Sri Mara Vijayotunga Varman, king of the Srivijaya Empire (based in present-day Sumatra, Indonesia), in memory of his father Sri Chudamanin Varman. The grant was originally made orally by Rajaraja Chola I and later permanently engraved on copper by his son Rajendra Chola I.
| Section | Language & Script | Number of Plates | Lines | Content |
|---|---|---|---|---|
| First Section | Sanskrit in Grantha script | 5 plates (both sides) | 111 lines | Genealogy of Chola rulers; mythological linkage to solar dynasty; royal titles and epithets |
| Second Section | Tamil | 16 plates | 232 lines | Administrative details of the land grant: village boundaries, tax exemptions, irrigation responsibilities, land measurement, grant recipients |
The Srivijaya Empire (Sailendra dynasty, c. 7th–11th century CE) was a Hindu-Buddhist thalassocratic (maritime) empire based in Sumatra (modern Indonesia). Sri Mara Vijayotunga Varman, a Srivijayan king, built the Chulamanivarma Vihara in Nagapattinam — documenting that Southeast Asian rulers maintained cultural and religious ties with South India through the Chola maritime network.
| Dimension | What the Plates Reveal |
|---|---|
| Political | Detailed Chola royal genealogy; administrative structure (Nadu, Velanadu); land rights and tenure system |
| Religious Pluralism | A Hindu emperor (Rajaraja Chola I — a devout Shaivite) patronised a Buddhist monastery built by a Malay Buddhist king — documenting India's tradition of religious coexistence |
| Maritime & Trade Networks | Proof of active diplomatic and trade relations between Chola Tamil Nadu and the Srivijaya Empire of Sumatra/Indonesia |
| Linguistic | One of the most significant surviving bilingual (Tamil + Sanskrit) records of medieval South India; Grantha script usage documented |
| Economic | Detailed records of land revenue, tax exemptions, and irrigation duties — primary source for Chola fiscal administration |
| Buddhist History | Documents the Chulamanivarma Vihara, which became a major Buddhist centre in South India; connected to 350+ Buddha bronzes found at Nagapattinam since 1856 |
The Tamil historical novel Ponniyin Selvan (Son of the River Ponni) by Kalki Krishnamurthy (published 1950–1954) explicitly mentions that the Leiden Plates are in Leiden University, Netherlands. This made the plates famous among Tamil readers for decades before official repatriation efforts began.
The Anaimangalam Copper Plates left India during the era of Dutch colonial presence on the Coromandel Coast (the southeastern coastline of India, including present-day Tamil Nadu and Andhra Pradesh). The Dutch East India Company (VOC — Vereenigde Oost-Indische Compagnie) was active on the Coromandel Coast and had a major settlement at Nagapattinam.
| Aspect | Detail |
|---|---|
| Dutch Company | VOC (Vereenigde Oost-Indische Compagnie) — Dutch East India Company, est. 1602 |
| Key Settlement | Nagapattinam (Tamil Nadu) — major Dutch trading post on the Coromandel Coast |
| Other Dutch Settlements | Masulipatnam (Andhra), Cochin (Kerala), Pulicat (Tamil Nadu) |
| Period of Activity | 17th–18th century on Coromandel Coast; lost Nagapattinam to British in 1781 |
| Relevance to Plates | Plates acquired during Dutch presence in Nagapattinam region, likely in early 18th century |
In a Rajya Sabha answer on 28 November 2024, the Ministry of Culture confirmed that India had raised the matter of the Leiden (Anaimangalam) Copper Plates at the UNESCO ICPRCP on 30th May 2024 (in addition to bilateral diplomatic channels). The minister cited the Antiquities and Art Treasures Act 1972 as the governing domestic law.

Under the Indian Constitution, heritage and antiquities are distributed across three lists: Item 67 of the Union List (ancient monuments of national importance), Item 12 of the State List (libraries, museums), and Item 40 of the Concurrent List (archaeological sites). The Antiquities and Art Treasures Act 1972 operates under the Union List.
| Instrument / Body | Year | Key Provision / Role |
|---|---|---|
| Antiquities (Export Control) Act | 1947 | First post-Independence law; no antiquity could be exported without a licence |
| UNESCO 1970 Convention | 1970 | International treaty prohibiting illicit import/export/transfer of cultural property; India ratified; basis for repatriation claims post-1970 |
| Antiquities and Art Treasures Act (AATA) | 1972 (enacted) / 1976 (commenced) | Act No. 52 of 1972; defines "antiquity" (≥100 years old); prohibits private export; only Central Government or authorised agencies can export; ASI grants licences |
| Antiquities and Art Treasures Rules | 1973 | Subordinate legislation to AATA; implementation framework |
| UNESCO ICPRCP | Est. 1978 | Intergovernmental Committee for Promoting Return of Cultural Property; India used ICPRCP to formally request Leiden Plates return (Oct 2023, 24th Session); recommendations advisory, not legally binding |
| UNIDROIT Convention on Stolen/Illegally Exported Cultural Objects | 1995 | Supplements UNESCO 1970 Convention; provides conditions for return of stolen/illegally exported cultural property |
| US-India Cultural Property Agreement (CPA) | July 2024 | Signed by US Ambassador Eric Garcetti and Indian Culture Secretary Govind Mohan; prevents smuggling and facilitates return; basis for 588+ artefacts returned from USA |
| Archaeological Survey of India (ASI) | Est. 1861 | Nodal body; works with Indian Embassies/MEA for retrieval of artefacts; administers AATA licensing |
Under the Antiquities and Art Treasures Act 1972: "Antiquity" = any coin, sculpture, painting, epigraph or work of art that has been in existence for not less than 100 years. For manuscripts and records: not less than 75 years. Export is completely prohibited for private persons.
The Netherlands introduced a national restitution policy for colonial-era objects in 2022. Under this policy, the Independent Colonial Collections Committee and Leiden University Libraries conducted a provenance study, concluded the Anaimangalam Plates rightfully belonged in India, and recommended return. This policy was a critical enabler for the 2026 repatriation.
| Scenario | Legal Position |
|---|---|
| Artefact exported after 1970 (post-Convention) | UNESCO Convention applies; ratifying parties must return illicitly exported items |
| Artefact exported before 1970 (pre-Convention) | Convention is non-retroactive — grey area; must rely on bilateral negotiations, ICPRCP recommendations, or domestic policies of holding country |
| Leiden Plates (exported ~18th century) | Pre-1970 — not covered by convention directly; returned via bilateral diplomatic channels + Netherlands' 2022 restitution policy + ICPRCP recommendation |
| Linked Concept | Connection to the Plates | UPSC Relevance |
|---|---|---|
| Chola Bronzes | Same dynasty; same Nagapattinam Buddhist connection (350+ bronzes found here); cire-perdue (lost-wax) casting technique | Art & Culture — frequently asked on Chola art |
| Great Living Chola Temples (UNESCO WHS) | Built by the same rulers who issued/inscribed the plates (Rajaraja I — Brihadisvara; Rajendra I — Gangaikonda) | UNESCO World Heritage — important for Prelims |
| Uttarameruru Inscription | Another important Chola copper plate record (Parantaka Chola); documents Chola village governance / local self-governance | Often asked alongside other Chola inscriptions |

Indian copper plate inscriptions (Tamrapattra) date from the Pallava dynasty (4th century CE) onwards. The Cholas produced over 10,000 copper and stone inscriptions, making them one of the most epigraphically rich dynasties in Indian history. Tamil copper-plate inscriptions record land grants, genealogies, wars, tax structures, and even village governance mechanisms.
| Inscription | Issued By | Key Content |
|---|---|---|
| Uttarameruru Inscription | Parantaka Chola I | Village self-governance (election procedures for village committees — early example of local democracy) |
| Tiruvalangadu Copper Plates | Rajendra Chola I | Detailed Chola royal genealogy; Sanskrit preamble; records grant to a goddess shrine at Tiruvalangadu |
| Anaimangalam Copper Plates | Rajaraja I (grant) / Rajendra I (inscribed) | Land grant to Chulamanivarma Vihara; bilingual; Srivijaya connection; religious pluralism |
| Leiden Grant (also called "Leyden Grant" in older literature) | Parantaka Chola I | Also in Leiden; distinct from Anaimangalam plates — records a grant to a goddess; important genealogical sections |
There are two distinct Leiden-related records: (1) The Anaimangalam Copper Plates (Rajaraja I era) — the set returned in 2026; and (2) The Leyden Grant of Parantaka Chola I — a separate, older set also once at Leiden. Do NOT confuse these. The 2026 repatriation refers specifically to the Anaimangalam Plates of Rajaraja/Rajendra Chola I.
The Netherlands formally handed over the Anaimangalam Copper Plates (Leiden Plates) to India on 15–16 May 2026, during PM Narendra Modi's visit to the Netherlands as part of his five-nation diplomatic tour. The ceremony was attended by Dutch PM Rob Jetten. PM Modi described it as "a joyous moment for every Indian," noting that the plates relate to Rajendra Chola I formalising his father Rajaraja I's commitment and "showcase the greatness of the Cholas, their culture and their maritime prowess."
The return followed a Leiden University provenance study by the Independent Colonial Collections Committee, which concluded the plates rightfully belonged in India. The study was facilitated by the Netherlands' 2022 national restitution policy for colonial-era objects — a domestic Dutch law that made institutional repatriation legally possible. India had raised the matter through bilateral diplomatic channels since 2012, and the Indian Embassy in The Hague had been in formal discussions with Dutch authorities since May 2019.
At the UNESCO ICPRCP 24th Session (October 2023), India formally requested inclusion of the Chola Copper Plates in its agenda; the committee validated India's claim of origin and encouraged Netherlands to negotiate return. A Rajya Sabha unstarred question (answered 28 November 2024) confirmed the Ministry of Culture had raised the matter at UNESCO ICPRCP on 30 May 2024 and was simultaneously pursuing bilateral talks with the Netherlands.
The repatriation was also attributed to a Writ Petition filed in 2019 by Advocate Jagannath before the Madras High Court, seeking a joint recovery team for stolen artefacts including the Anaimangalam Plates. Temple activist TR Ramesh noted that this persistent legal effort — alongside government diplomatic action — contributed to the eventual return. The petition listed the plates among artefacts taken from Chudamani Vihara, a Buddhist monastery in Nagapattinam.
Separately, the USA returned 657 Indian antiquities worth $14 million to India in three phases: 612 items in November 2024, 26 in July 2025, and the final 19 on 28 April 2026. Many were linked to traffickers Subhash Kapoor and Nancy Wiener. The formal handover was in New York, in the presence of India's Consul General. Manhattan DA Alvin Bragg highlighted the scale of the international smuggling networks dismantled.
The Anaimangalam Copper Plates combine four high-frequency UPSC themes: (1) Chola dynasty (Art & Culture / Medieval History), (2) Heritage repatriation policy (Antiquities Act, UNESCO conventions), (3) India's cultural diplomacy (bilateral agreements, PM Modi's foreign visits), and (4) Srivijaya Empire & maritime trade. Expect at least 1 MCQ on this topic in Prelims 2026–2027.
| Statement | Verdict | Reason / Correct Fact |
|---|---|---|
| The Anaimangalam Copper Plates were issued by Rajendra Chola I | ❌ Partly False | The original land grant was issued by Rajaraja Chola I (regnal year 21). The plates were later inscribed on copper by his son Rajendra Chola I to make the grant permanent. |
| The plates record a grant to a Hindu temple at Nagapattinam | ❌ False | The grant was to the Chulamanivarma Vihara, a Buddhist monastery — not a Hindu temple. This documents Chola religious pluralism. |
| The Chulamanivarma Vihara was built by a Chola king | ❌ False | It was built by Sri Mara Vijayotunga Varman, ruler of the Srivijaya Empire (present-day Indonesia) — not by a Chola king. The Chola king merely patronised it. |
| The plates are written entirely in Tamil | ❌ False | The plates are bilingual — Sanskrit (Grantha script, 5 plates, 111 lines) + Tamil (16 plates, 232 lines). |
| The plates have been at Leiden University since the 17th century | ❌ False | The plates entered Leiden University in 1862 (19th century), donated by Hamaker family descendants. |
| India's 2019 Madras HC PIL was the only mechanism used to reclaim the plates | ❌ False | Multiple channels: bilateral diplomacy (since 2012), UNESCO ICPRCP (Oct 2023), the PIL, and the Netherlands' 2022 restitution policy all contributed. |
| The UNESCO 1970 Convention directly mandated the return of the Leiden Plates | ❌ False | The Convention is non-retroactive. Since the plates left India in the 18th century (pre-1970), the Convention does not directly apply. Return was via bilateral diplomacy and Netherlands' domestic 2022 policy. |
| Rajaraja Chola I was a follower of Buddhism who built the Nagapattinam monastery | ❌ False | Rajaraja I was a devout Shaivite (follower of Shiva). He patronised the Buddhist monastery — an example of his religious tolerance — but did not build it. The builder was the Srivijayan king. |
The grant was issued by Rajaraja Chola I but inscribed onto copper by Rajendra Chola I. UPSC may test this with "Who issued the Anaimangalam plates?" — both names are partially correct, but the original grant giver is Rajaraja I; the copper inscriber is Rajendra I.
There are TWO distinct records once associated with Leiden: (1) Anaimangalam Copper Plates (Rajaraja I era) — the set returned in 2026; (2) Leyden Grant of Parantaka Chola I — a separate, older record. The 2026 news refers exclusively to the Anaimangalam set. Do not mix these up.
The monastery is the Chulamanivarma Vihara (also: Chudamani Vihara). "Chudamani" means "crest jewel" in Sanskrit. "Chulamanivarma" is the name of the Srivijayan king's father (Sri Chudamanin Varman), in whose memory the monastery was built. UPSC may confuse students with the slight name variations.
Srivijaya Empire was based in Sumatra, Indonesia (not Malaysia or Cambodia). Its ruler built a monastery in India. The Cholas later conducted a naval raid on Srivijaya in 1025 CE under Rajendra I — yet the cultural and religious ties documented in the Anaimangalam Plates predate this military conflict.
The Antiquities and Art Treasures Act was enacted on 9 September 1972 but commenced on 5 April 1976 (Sikkim: 1 June 1979). It repealed the older Antiquities (Export Control) Act, 1947. Assented to by President V.V. Giri. UPSC may test: "Who gave assent to the Antiquities Act 1972?" → President V.V. Giri.
Some reports say "300 years in Dutch possession" (since early 18th century when Camper acquired them) while others say "160 years at Leiden University" (since 1862 donation). Both are technically correct for different reference points. The plates left India in the early 18th century (~1703–1712) and reached Leiden University in 1862.
For statement-based MCQs on this topic, the most common traps are: (1) who issued vs. who inscribed the plates, (2) Buddhist monastery vs. Hindu temple, (3) retroactivity of UNESCO 1970 Convention, (4) Leiden Plates as exclusively Tamil (wrong — bilingual). Eliminate options that state any of these wrongly.
