Kingdom of Cochin (also known as Perumpadappu Swaroopam, Mada-rajyam, Gosree Rajyam, or Kuru Swaroopam; Malayalam: കൊച്ചി or പെരുമ്പടപ്പ്‌ ) was a late medieval Hindu kingdom and later Princely State on the Malabar Coast, South India. Once controlling much of the territory between Ponnani and Kochi in Malabar, the Cochin kingdom shrank to its minimal extent as a result of invasions by the Zamorin of Calicut. When Portuguese armadas arrived in India, Cochin was in vassalage to Zamorin and was looking for an opportunity to break away. King Unni Goda Varma Tirumulpadu (Trimumpara Raja) warmly welcomed Pedro Álvares Cabral on 24 December 1500 and negotiated a treaty of alliance between Portugal and the Cochin kingdom, directed against the Zamorin of Calicut. Cochin became a long-time Portuguese protectorate (1503–1663) providing assistance against native overlords. After the Portuguese, the Dutch East India Company (1663–1795) followed by the English East India Company (1795–1858, confirmed on 6 May 1809), protected the Cochin state.
