Ohrid Agreement

The Ohrid Framework Agreement (Albanian: Marrëveshja e Ohrit) was the peace deal signed by the government of the Republic of Macedonia and ethnic Albanian representatives on 13 August 2001. The agreement ended the armed conflict between the National Liberation Army and the Macedonian security forces and set the groundwork for improving the rights of ethnic Albanians.

The Agreement also included provisions for altering the official languages of the country, with any language spoken by over 20% of the population becoming co-official with the Macedonian language on municipal level. Currently only Albanian with an approximate 25% of the population fulfils this criterion. According to the document, the version in English language is the only authentic version of the Ohrid Framework Agreement.
