Princess Astrid and Prince Lorenz have five children, who bear the title "Prince/Princess of Belgium" (in each of the three official languages) as members of the Belgian royal family and Archduke/Archduchess of Austria:
Astrid was formerly President of the Belgian Red Cross, a position which ended on 31 December 2007. She declined to stand again for election to the role in light of internal struggles in the organisation in reconciling its French-speaking and Flemish branches, each of which seeks greater autonomy. The princess is also a colonel in the Medical Component of the Belgian Armed Forces. Her official residence is the Royal Castle of Laeken on the edge of Brussels.
Princess Astrid has been for many years a fierce advocate for landmine survivors rights, participating actively in the work of the Anti-Personnel Mine Ban Convention, also known as the Ottawa Treaty, since Belgium joined in 1998. In 2013, the Princess was named Special Envoy of the Convention, and has promoted the acceptance of a global ban on landmines and promoted the rights of survivors in various UN meetings.
