Talk:Illyrian movement

official dates

 * . . . around the years of 1835–1863 (there is some disagreement regarding the official dates from 1935 to 1970).

What, if anything, does the parenthesis mean? Was there a dispute among historians that arose in 1935 and was resolved in 1970? Does a movement have official dates? Please reword! —Tamfang (talk) 20:22, 31 December 2019 (UTC)
