[Q]: Passage: After the War of Independence and truce called in July 1921, representatives of the British government and the Irish treaty delegates, led by Arthur Griffith, Robert Barton and Michael Collins, negotiated the Anglo-Irish Treaty in London from 11 October to 6 December 1921. The Irish delegates set up headquarters at Hans Place in Knightsbridge, and it was here in private discussions that the decision was taken on 5 December to recommend the treaty to Dail Eireann.The Second Dail Eireann narrowly ratified the Treaty. In accordance with the treaty, on 6 December 1922 the entire island of Ireland became a self-governing Dominion called the Irish Free State . Under the Constitution of the Irish Free State, the Parliament of Northern Ireland had the option to leave the Irish Free State one month later and return to the United Kingdom. During the intervening period, the powers of the Parliament of the Irish Free State and Executive Council of the Irish Free State did not extend to Northern Ireland. Northern Ireland exercised its right under the treaty to leave the new Dominion and rejoined the United Kingdom on 8 December 1922. It did so by making an address to the King requesting, "that the powers of the Parliament and Government of the Irish Free State shall no longer extend to Northern Ireland." The Irish Free State was a constitutional monarchy sharing a monarch with the United Kingdom and other Dominions of the British Commonwealth. The country had a governor-general , a bicameral parliament, a cabinet called the "Executive Council", and a prime minister called the President of the Executive Council.

[Q]: Passage: In 1762, the population of the Dutch colony of Berbice included 3,833 enslaved Blacks, 244 enslaved Amerindians or indigenous people, and 346 whites. On 23 February 1763, slaves on Plantation Magdalenenberg on the Canje River in Berbice rebelled, protesting harsh and inhumane treatment. They torched the plantation house, then went to other plantations to mobilize other enslaved Africans to join the rebellion. Cuffy, an enslaved man at Lilienburg, another plantation on Canje, is said to have organized them into a military unit. As plantation after plantation fell to the slaves, the Dutch settlers fled northward and the rebels began to take over control of the region. For almost a year, the rebels held on to southern Berbice, while the whites were able to hold on to the north. Eventually only about half of the white population that had lived in the colony remained. The rebels came to number about 3,000 and threatened European control over the Guianas. Other key figures among the rebels include Atta, Accara, and Accabre. The insurgents were eventually defeated in the spring of 1764 with the assistance of troops from neighbouring French and British colonies and from Europe.
