In the early 19th century, the Al Abu Falasa dynasty (part of the House of Al-Falasi)[REF] of the Bani Yas tribe established Dubai, which remained a dependent of Abu Dhabi until 1833 [REF].
Dubai suffered economically after 1920 due to the collapse of the pearl industry, the Great Depression of the 1930s, and the loss of extensive trade networks during World War II.
