In the bachelor’s thesis, I will analyze the development of the electoral system in Albania and the Republic of Macedonia from the fall of communism in 1990 to 2014 and its consequences on the number of (mostly younger) political parties represented in the Parliament. In the period of transition between the communist one-party system and democratic multiparty system, which is still ongoing, both countries have often changed the electoral system and the electoral legalization. For twenty years, Albania and Macedonia have held eight parliamentary elections and none of them were held in the same electoral system. First elections in Albania were held by a proportional electoral system. Then, the next five elections were held by a mixed electoral system and the last two by a proportional electoral system. The same number of elections was held by the Republic of Macedonia during the same period. The first two elections were held by the majority electoral system, the third by a mixed electoral system, and the last five by a proportional electoral system. In addition to the electoral system, both countries often changed electoral elements. Albania changed the electoral threshold most often and Macedonia changed the number of constituencies and the constituency. This appears to point to electoral engineering, which in both countries is an instrument for achieving the desired electoral results of certain, most dominant parties. From the point of theory, the change of electoral system is interesting and will help us to analyze the consequences of the various electoral systems and changing the electoral rules to the number of parties and the proportion of seats of smaller parties in the parliament of both countries.
