Input: passage: The flags of Romania and Chad are identical aside from the blue strip on the left, which is slightly darker in the Chadian flag. Romania used the flag from 1866, while in that form appeared for the first time in Wallachia, being officially in use in 1848. Chad began to use its present flag in 1960, after it achieved independence from France. At that time, the Chad and Romanian flags were distinguishable by the latter's inclusion of the Coat of Arms of the Socialist Republic of Romania at the Romanian flag's centre. However, in 1989, the coat of arms was removed entirely after the revolution which overthrew Nicolae Ceausescu.
