In November 1659, Mary sent her son to study at Leiden University. On 14 May 1660, the Dutch parliament informed Mary, who was in Breda, about the restoration of the monarchy in England and the accession to the throne of her brother Charles (henceforth King Charles II). A few days later she took part in the celebrations at The Hague on this occasion. Mary henceforth occupied the fifth place in the line of succession to the English throne, and therefore the attitude towards the princess herself in the Netherlands became much more tolerant: in all the cities where Mary and William III were passing through or attended solemn events, they were greeted with royal honors. After the Stuart Restoration it was proclaimed that the Act of Seclusion was void, since no longer existed the English Republic, and in 1660, Mary, united with her mother in law, tried to convince the states of several provinces acknowledge William III as future Stadtholder, but many refused at first.
