Around the 1870s, Yap Ah Loy , emerged as leader, and became responsible for the growth of the town. He began to develop Kuala Lumpur from a small unknown place into a mining town with economic boom. In 1881, a flood swept through the town following a fire which engulfed it earlier. These successive problems destroyed the town's structures of wood

In 1896, Kuala Lumpur was chosen as the capital of the newly formed Federated Malay States.
