The Federation of Malaya was established in 1948, uniting several states on the Malay Peninsula under a single administration. It included the Federated Malay States and the Unfederated Malay States, aiming to promote economic development and political stability. The federation was a response to the challenges faced during the post-World War II period. In 1957, the Federation of Malaya gained independence from British colonial rule, leading to the formation of the modern nation of Malaysia. The federation played a crucial role in shaping the political landscape of the region and laid the groundwork for future unity among the Malay states.
