Ruled by the Al Thani family since the mid-1800s, Qatar within the last 60 years transformed itself from a poor British protectorate noted mainly for pearling into an independent state with significant oil and natural gas revenues. Former Amir HAMAD bin Khalifa Al Thani, who overthrew his father in a bloodless coup in 1995, ushered in wide-sweeping political and media reforms, unprecedented economic investment, and a growing Qatari regional leadership role, in part through the creation of the pan-Arab satellite news network Al-Jazeera and Qatar's mediation of some regional conflicts. In the 2000s, Qatar resolved its longstanding border disputes with both Bahrain and Saudi Arabia and by 2007 had attained the highest per capita income in the world. Qatar did not experience domestic unrest or violence like that seen in other Near Eastern and North African countries in 2011, due in part to its immense wealth. In mid-2013, HAMAD peacefully abdicated, transferring power to his son, the current Amir TAMIM bin Hamad. TAMIM is popular with the Qatari public, having prioritized improving the domestic welfare of Qataris, including establishing advanced healthcare and education systems and expanding the country's infrastructure in anticipation of Doha's hosting of the 2022 World Cup. Recently, Qatar’s relationships with its neighbors have been tense. Following the outbreak of regional unrest in 2011, Doha prided itself on its support for many popular revolutions, particularly in Libya and Syria. This stance was to the detriment of Qatar’s relations with Bahrain, Saudi Arabia, and the United Arab Emirates (UAE), which temporarily recalled their respective ambassadors from Doha in March 2014. TAMIM later oversaw a warming of Qatar’s relations with Bahrain, Saudi Arabia, and the UAE in November 2014 following Kuwaiti mediation and signing of the Riyadh Agreement. This reconciliation, however, was short-lived. In June 2017, Bahrain, Egypt, Saudi Arabia, and the UAE (the "Quartet") cut diplomatic and economic ties with Qatar in response to alleged violations of the agreement, among other complaints. This impasse continues.
