Quezon arrived in Washington D.C. in December 1933 to negotiate independence for the Philippines. In January 1934, he proposed either independence within 2-3 years with limited free trade, or independence in 6 years with autonomy and special trade relations after. The Tydings-McDuffie Act was passed in 1934, establishing a 10 year transition period to full independence for the Philippines in 1946 and a new constitution was ratified in 1935. Quezon and Osmena were elected as the first president and vice president of the new Philippine Commonwealth. However, economic difficulties emerged as the country struggled with inadequate education systems and unfulfilled promises of land reform during this interim period of self-governance.
