The alliance between the Bharatiya Janata Party and the Janata Dal (United) in Bihar is under pressure after BJP veteran BJP leader L K Advani announced his resignation. BJP leader Narendra Modi, who will be leading his party's 2014 election campaign, and Bihar chief minister Nitish Kumar, JD-U's most important leader, have had a strained relationship and with the Advani controversy looming they might end pretending to be partners. Here is a timeline of the two parties' alliance.
1998: Established in May 1998 with 13 constituent parties at that time with JD (U) president Sharad Yadav, as its convenor and Atal Bihari Vajpayee as its chairman.
1999: NDA in Bihar, including BJP and JD (U), won 23 and 18 seats respectively out of 54 seats in the then united Bihar.
2000: March 3: Nitish Kumar appointed chief minister but resigns seven days later due to fractured mandate and failing to prove majority.
2004: NDA partners JD (U) and BJP won 6 and 5 Lok Sabha seats respectively out of 40 seats in Bihar. Nitish Kumar becomes railway minister in A B Vajpayee cabinet
February 2005: Assembly polls: Threw up a fractured mandate with JD (U) winning 55 seats and BJP garnering 37 seats out of 243 seats. President's rule imposed. Polls announced again due to fractured mandate.
November 2005 Assembly polls: The NDA won with a clear majority with JD (U) winning 88 seats and BJP 55 seats in the 243-member Bihar assembly. NDA's projected leader, Nitish Kumar became the chief minister with Vajpayee and LK Advani's blessings.
2009 Lok Sabha elections: The NDA won 20 Lok Sabha seats and 12 seats out of 40 seats in Bihar. Nitish Kumar prevents Narendra Modi to come to Bihar for poll campaign saying Bihar has its own Modi referring to Deputy CM Sushil Kumar Modi

June 12, 2010: Nitish Kumar cancelled a dinner he was to host for the BJP leaders attending national executive meeting in Patna, apparently miffed over a series of full page advertisements that appeared in vernacular dailies showing him with Gujarat Chief Minister Narendra Modi hands clasped in a victory sign. He also threatened legal action against the agency that had released the advertisements.
June 20, 2010: A week after Nitish Kumar cancelled a dinner for BJP leaders, he returned Rs 5 crore donated by Gujarat government for Kosi flood relief in 2008.
October 11, 2011: Despite Narendra Modi and RSS's non-committal stand, LK Advani starts on a Jan Chetna yatra from Sitabdiara in Bihar instead of Somnath in Gujarat. Nitish Kumar flags it off from JP's village. The yatra was a bid by Advani to pitch for prime ministership all over again.
