In the late 1980s, the liberalization of USSR led to the emergence of long-repressed nationalist movements and ethnic disputes within the diverse republics of the Soviet Union. Along with several other Soviet republics, Moldova started to move towards independence. Republic of Moldova is a unitary parliamentary representative democratic republic. The country's supreme central legislative body is the unicameral Moldovan Parliament, which is rather young, dating from 1990, as the first democratic elections for the local parliament were held in 1990. The Parliament adopted the Declaration of Sovereignty of the „Soviet Socialist Republic Moldova”, which, among other things, stipulated the supremacy of Moldovan laws over those of the Soviet Union. In 1991, the Moldovan parliament changed the name of the republic from „Moldavian SSR” to „Republic of Moldova”. Moldova then seceded from the USSR and became a sovereign, independent state. Although the young Moldovan parliament experienced some crisis moments, it is considered to achieve success in establishing the legislative basis of the newly formed state. In Moldova, as in other former Soviet Republics, the Parliament is a creation of social practice, a result of the dissolution of the Soviet Union. Based on these beliefs, we can agree that the need for such research is justified. Parliamentarism as a form of government and political influence in studies of both historical and contemporary points of view is a subject of this presentation. From this point of view, in the modern world, we are increasingly seeing a persistent manifestation of democratic functioning and organization of power, based on the fundamental principles of law. The Constitution of the Republic of Moldova is that country's supreme law. In general, we should note that there is a trend that actually reflects a series of states that have entered at the path of democratic development and definition of the state of law.
