When was the first Legislative Assembly held?

The first Legislative Assembly in the Cayman Islands was held in December 1831. This assembly marked a significant development in the political evolution of the islands, establishing a framework for local governance within the British colonial system. The decision to convene this assembly was part of a broader trend during the 19th century where many British colonies were moving towards more representative forms of government. The assembly allowed for the local population to have a say in the legislative process, which was an important step in the progression towards self-governance in the Cayman Islands.

Understanding the timeline of legislative developments is vital for comprehending the historical context of governance in the region. The other timeframes provided do not correlate with the documented history of the Cayman Islands' legislative processes, making December 1831 the correct answer in establishing this important milestone in Cayman history.
