Answer: A major escalation of US military involvement in the Vietnam War.
Detail:
The Gulf of Tonkin Resolution was a measure passed by US Congress that allowed the US President to make military actions, like increase troops, without formal declaration of war. It led to huge escalation of US involvement in the Vietnam War. The resolution was passed by Congress in August, 1964, after alleged attacks on two US naval ships in the Gulf of Tonkin. The key wording in the resolution said:
<em>Resolved by the Senate and House of Representatives of the United States of America in Congress assembled, that the Congress approves and supports the determination of the President, as Commander in Chief, to take all necessary measures to repel any armed attack against the forces of the United States and to prevent further aggression.</em>
That resolution served as a blank check for President Johnson to send troops to whatever extent he deemed necessary in pursuance of the war. Between 1964 and the end of Johnson's presidency in 1969, US troop levels in Vietnam increased from around 20,000 to over 500,000.
The presence of African culture in Brazil resulted in the practice of slavery during the colonial period. Africans were brought in Brazil during the colonial period to work as labours in plantations and other purposes. Slaves not only worked but introduced African culture, which they brought with them. Music, food and samba are part of African culture.
At the start of the Revolution the largest denominations were Congregationalists (the 18th-century descendants of Puritan churches), Anglicans (known after the Revolution as Episcopalians), and Quakers. But by 1800, Evangelical Methodism and Baptists, were becoming the fasting-growing religions in the nation.
