Dominated by the Thani family for almost 150 years, the mainly barren country was a British protectorate until 1971, when it declared its independence after following suit with Bahrain and refusing to join the United Arab Emirates.
In 1995 Crown Prince Hamad bin Khalifa deposed his father to become emir and during his reign introduced some liberal reforms.
Press freedom was extended and the Qatari satellite TV station Al-Jazeera has become one of the most important broadcasters in the Arab world.
Elections in 1999 for a 29-member municipal council were the first in which Qatari women were allowed to vote and stand for office.
