Abstract
The contribution is a brief analysis of the concept of "solidarity" in the context of European Union law. Since it is a topic that is practically undeveloped, especially in Czech legal literature, it is first necessary to give a brief explanation of the meaning of this notion in the non-legal field and its penetration into the legal field and its development in EU law.
Secondly, it defines the essence, content and function of solidarity and analyses its relationship with similar general categories of EU law, including its basic principles, and fundamental human rights. The article thus defines the scope of the concept of solidarity, which includes not only obligations, but also rights that operate not only between member states, member states and the institutions of the European Union, but also in some cases towards individuals.
The contribution comes to the conclusion that solidarity is a key category, which has the status of a meta-principle of a multi-layered structure. It forms the basis of a legal and constitutional community such as the European Union, and also as a part of a legal norm expressing specific assistance.
