while the Emperor was on a visit to Brazil. The coup leaders allegedly detained Crown Prince Asfaw Wossen in the Imperial Palace, and the following morning, having secured control over most of the capital, then allegedly compelled the Crown Prince to read a radio statement, in which he accepted the crown in his father's place and announced a government of reform.
