Modern maps show the location of former land borders. But worldwide, as many as 10 million people are classified as stateless.
Now, a female founder from Munich without official nationality is aiming to change all that with her non-profit-organisation.
Having no personal identification or passport makes everything tricky, not just travel.
People can be stateless for a variety of reasons. Refugees, for instance, may lack adequate documentation in their new countries.
The initiative offers the first global online community with information and support for those affected and their allies.
A new exhibition, meanwhile, is helping promote the subject.
The founder is also working with international networks and politicians to help create equal rights for the stateless community.
