Donation of Bartolomeu

The Donation of Bartolomeu (or the Cessation of Nagasaki) was a legal act issued on June 9, 1580, by the Kirishitan daimyō Ōmura Sumitada (baptized as Dom Bartolomeu). Through this charter, Sumitada ceded the port towns of Nagasaki and Mogi in perpetuity to the Society of Jesus (Jesuits).

Intended both to secure a safe haven for Christians and to protect Sumitada's domains during the chaos of the Sengoku period, the donation gave Nagasaki a unique character, setting it apart from all other Japanese cities.

Under Jesuit administration (1580–1587), Nagasaki grew into a principal hub for commerce and missionary activity. This administration lasted until the territory was reclaimed by Toyotomi Hideyoshi.

The fusion of Japanese and European cultures became a rare experience in history, especially considering the isolation and resistance to foreign influence often practiced by the Japanese.
