Qatari literature traces its origins back to the 19th century. Originally, written poetry was the most common form of expression. Abdul Jalil Al-Tabatabai and Mohammed bin Abdullah bin Uthaymeen, two poets dating back to the early 19th century, formed the corpus of Qatar's earliest written poetry. Poetry later fell out of favor after Qatar began reaping the profits from oil exports in the mid-20th century and many Qataris abandoned their Bedouin traditions in favor of more urban lifestyles.
