Voting right is the most important political right an individual can have, and usually it is provided to citizens through the Constitution of the State. In this day, every country has many emigrants, as a result of many migrations. The voting right of emigration is a topic discussed in the 20th century, which is still going on today, and various discussions are being held. Some countries narrow this political right to emigrated citizens, while others are wider and strive to include as many populations outside the borders of the state into political activation. In this paper, it seeks to define the social concept of “diaspora”, to describe the development of the croatian diaspora and its influence on political elections in the Republic of Croatia. The electoral law will be summed up as political law and will show legislative arrangements in the Republic of Croatia and in Europe and the world. Through comparative analysis we will find various solutions to this political and legal issue and ways to incorporate the diaspora into the political life of the country of origin. The possible solution for the Republic of Croatia will be suggested and its arrangement of this issue in a more efficient way than previously arranged. Electronic voting will be presented as a new method of voting in the elections.
