The document summarizes the history and development of the Indian economy from ancient times to present day. It discusses how the economy was negatively impacted during British colonial rule but began to grow after independence through import substitution industrialization and nationalization of key industries. Economic reforms since 1991 opened the economy to foreign investment and global trade, leading to strong growth rates of around 7% annually over the past few decades and positioning India as the 7th largest economy globally. Recent years have seen some slowing but growth is projected to remain around 7-8% through 2016-17.
