Dawn.com retraces the major events from that fateful point in history and Musharraf's political descent since then.
Eight years after then-Army chief General Pervez Musharraf seized power in 1999 and declared himself the country's chief executive, a new crisis erupted in 2007 when he imposed emergency in the country once more.
In a brief but dark period that followed, the Constitution remained suspended from November 3 to December 15 and several judges, including the chief justice, were detained.
In the proclamation order for the emergency, Musharraf, who had become a self-appointed president in June 2001, cited members of the superior judiciary "working at cross purposes with the executive and legislature in the fight against terrorism and extremism" as grounds for calling an emergency.
