Patil had undergone a surgery for oral cancer at Breach Candy Hospital last December.
Fondly called 'Aaba' in political circles, he was considered very close to NCP chief Sharad Pawar.
Patil was elected to the Legislative Assembly for the first time in 1990 and appointed Rural Development Minister in the Congress-NCP government in 1999. He was allotted the important Home portfolio in 2003 after the then Deputy Chief Minister Chhagan Bhujbal, who held it, resigned in the wake of allegations of his involvement in the Telgi scam. He was made Deputy Chief Minister in 2004.
He had to step down as Home Minister after his remarks made in the aftermath of the 26/11 attacks that "small incidents do happen in big cities" triggered an outrage.
Patil was appointed Home Minister for a second time in 2009 after the Congress-NCP combine retained power in the state.
He was also the man behind the controversial decision to ban dance bars in Mumbai and other parts of Maharashtra.
