According to Anatol Petrencu, during the most of the Romanian period, Bessarabia benefited by democracy, with a multiparty and a modern electoral system, based on the 1923 Constitution and laws. In November 1919, Romania elected the first post-war parliament based on the proportional representation of the mandates according to the number of the population. As of mid 1919, the population of Bessarabia was estimated at around 2 million. With a voter turnout of 72.2%, the Bessarabians elected and sent to the Romanian Parliament 90 deputies and 37 senators.
