The origins of the Schengen Area - historical scrutiny
The Schengen Area is one of the pillars of the European project. But it has been affected by several difficulties: the serious consequences of the global economic and financial crisis (2008-2018), growing concerns over external migratory pressure and the question of enlargement, fears of social dumping and, since March 2020, the COVID-19 crisis. Identifying these obstacles is vital so that pragmatic solutions can be found without jeopardising the founding principle.
