When did the Cayman Islands become internally self-governing?

The Cayman Islands first became internally self-governing in July 1959, while they were still a dependency of Jamaica.1

Following Jamaica's independence in 1962, the islands reverted to direct British rule before a new constitution was approved in 1972, which provided for autonomy regarding most domestic issues. The current constitutional framework, which provides for internal autonomy under a governor, a cabinet, and a Parliament, took effect in 2009 and was subsequently amended in 2020.12
