The article examines the evolution of the concept of protective democracy and ways of its implementation in political and legal practice. It is emphasized that in the course of historical development, the concept of democracy as one of the oldest means of organizing political power underwent significant changes caused by the evolution of society, legal and political systems, which affected its interpretation and implementation. The ideas that arose around this concept were studied, considering them from different perspectives - from historical to modern. It is shown that the primary and consolidated ideas about protective democracy arose at the turn of the XVII-XVIII centuries, when democracy began to be considered as a means by which citizens can protect themselves from excessive state control. It is noted that in the process of formation of the concept of protective democracy, political and legal ideas about the right to vote as a tool for the implementation of government accountability played a significant role, since democratic institutions and procedures need protection from abuse of power to ensure their stability and effectiveness. It is emphasized that the right to vote, as a key element of democracy, plays a significant role in this concept, as it is the main mechanism for expressing the will of the people and establishing the accountability of the government to the citizens. It is noted that ensuring wide access to voting ensures a higher level of government legitimacy and reduces the likelihood of its authoritarian tendencies. It is shown that political and legal ideas about the right to vote played a key role in the formation of the concept of protective democracy, emphasizing the need to protect and support this fundamental right to ensure the stability and effectiveness of democratic systems. Attention is paid to the contribution to the concept of defensive democracy by such outstanding thinkers and politicians as John Locke, Jeremy Bentham, James Mill and James Madison.
