Manuel L. Quezon was the legislator who became affiliated with the American leaders.

Manuel L. Quezon was a prominent figure in Philippine history, known for his role in advocating for the country's independence from American rule. He served as the first President of the Commonwealth of the Philippines from 1935 until his death in 1944. Quezon was initially affiliated with American leaders due to his position in the Philippine Legislature during the early 20th century, a time when the Philippines was a territory of the United States.

His political career began as a member of the Philippine Assembly, which was created under the Jones Law of 1916, establishing a form of self-governance for the islands. Quezon worked closely with American officials, including Presidents William Howard Taft and Franklin D. Roosevelt, to push for greater autonomy and eventual independence for the Philippines. He advocated for social justice, land reform, and economic development to uplift the Filipino people.

In summary, Quezon's affiliation with American leaders was primarily strategic, as he sought to gain support for the Philippines' transition to self-governance and independence, marking a significant chapter in the nation's history.
