38As is apparent from recitals 1 and 45 of Regulation No 883/2004, the aim of that regulation is to coordinate the national social security systems of the Member States in order to guarantee that the right to the free movement of persons can be exercised effectively and, thereby, to contribute towards improving the standard of living and conditions of employment of persons who move within the European Union, while modernising and simplifying the rules contained in Regulation No 1408/71 (see, to that effect, judgment of 16 July 2020, AFMB and Others, C‑610/18, EU:C:2020:565, paragraph 63).
