Othello was frequently performed as an Arab Moor during the 19th century. He was first played by a black man on the London stage in 1833 by the most important of the nineteenth-century Othellos, the African American Ira Aldridge who had been forced to leave his home country to make his career. Regardless of what Shakespeare intended by calling Othello a "Moor" – whether he meant that Othello was a Muslim or a black man or both – in the 19th century and much of the 20th century, many critics tended to see the tragedy in racial terms, seeing interracial marriages as "aberrations" that could end badly. Given this view of "Othello", the play became especially controversial in apartheid-era South Africa where interracial marriages were banned and performances of "Othello" were discouraged.
