The conundrum on the constitution of Union citizenship is progressively coming to the fore with the development of the case law of the European Court of Justice. This research delves into the thematic of what the status of EU citizenship and the associated right to freedom of movement yield for children in the Union. The topic has received little attention and even if discussed, children's issues are frequently tied to the rights of their parents. The work adopts an alternative approach by examining children's independent position in relation to both the status of EU citizenship and the right to freedom of movement. It demonstrates that the evolution of the influence of the concept of European citizenship and the related freedoms has strengthened children's autonomous status and secured some of their special kinds of interests.
