Borders have always been functional: they protect, they signify that a certain line should not be crossed. This is true not only for the everyday coexistence of people, but also for states, countries, cities or regions. However, new approaches – such as the creation of the European Union – may be regarded as a groundbreaking phenomenon of peaceful intergovernmental organization: Here, within a few years, any dialogue including unhindered travel, trade and movement of up to 508 million people from the most diverse territories has been made possible. This could also be used to connect continents and generally turn borders into bridges so that people and ideas can exchange freely.
