Archeological discoveries, inscriptions and a collection of exquisite pottery which were found in scattered areas in the country have proven that the land of Qatar was populated as early as 4000 BC.
-In the 5th century BC the Greek historian Herodotus referred to the seafaring Canaanites as the original inhabitants of Qatar. Further, the geographer Ptolemy showed in his map of the Arab World "Qatara" as believed to refer to the Qatari town of "Zubara", which has acquired the fame of being one of the most important trading ports in the Gulf region at the time.
-Qatar played an important role in the Islamic civilization when its inhabitants participated in the formation and provision of the first naval fleet, which was assembled to transport the army during the Islamic conquests.
-Under the Abbasid State during the 8th century AH (the 14th century AD), Qatar experienced great economic prosperity as can be gleaned from the inscriptions of (Murwab) Fort on the western coast of the peninsula, which bears the marks of the Abbasid architectural style.
-During the 16th century AD, the Qataris aligned with the Turks to drive out the Portuguese. Subsequently, Qatar alongside with the whole regions of the Arabian Peninsula came under the Ottoman Empire rule for about four successive centuries.
-In the aftermath of the 1914 First World War, the Turkish rule in Qatar came to an end and Qatar signed a protection treaty with Britain in 1916. However, the British influence in the country was limited to supervision of some administrative matters.
-In the early 18th century, Qatar was ruled by the Al-Thani family, who take their name from their ancestor, Thani, father of Skeikh Mohammad Bin Thani, who was the first Sheikh to rule over the Qatari peninsula during the mid 19th century.
-The Al-Thani family was among a tribal group who settled for a long time at the "Gibrin" oasis in the southern Najd, before their arrival at Qatar during the early 18th century. It is a branch of the Bani Tamim tribe, whose descent can be traced back to Mudar Bin Nizar. Initially they settled in Zubara in the north of the peninsula, moving to Doha in the mid 19th century under the leadership of Sheikh Mohammad Bin Thani.
-In 1878 Sheikh Jassim Bin Mohammad succeeded his father Sheikh Mohammad bin Thani.
-In 1913 Sheikh Abdallah bin Jassim, came to power. It was in his time when oil was first discovered in Qatar.
-In 1940 Sheikh Hamad Bin Abdullah ruled Qatar until 1948.
-In 1949 Sheikh Ali bin Abdallah came to power and ruled until 1960. And in that year, Sheikh Ahmad Bin Ali ruled Qatar and his reign continued until 1972. -In 1972, Sheikh Khalifa bin Hamad Al Thani ruled the country. On September 3rd, 1971 Qatar became independent.
-In 1995 Sheikh Hamad bin Khalifa Al Thani assumed power with the support and blessings of the ruling family and the Qatari people.
