What do you mean by that? There were of course borders, and they were certainly enforced.
Until the late 18th century travellers were more likely to be monitored at the district or parish level. During the French revolutionary wars the Jacobins began to issue foreign travellers with a carte de sureté on arrival at the French border, but these early ‘passports’ were dependent on the ideological affiliations of the holder rather than their nationality and subsequently fell into disuse after the Napoleonic Wars.
For much of the 19th century border control was sporadic and often non-existent, as millions of people migrated from Europe to the New World or within Europe itself without any passports or documentation. In 1942 the Austrian writer Stefan Zweig recalled the amazement of young people when he told them he had travelled across the world without a passport before the First World War.
The situation had started to change following the global economic slump in 1873, when governments began to introduce immigration controls based on nationality and ethnicity for the first time. In 1882 the US government passed the first Chinese Exclusion Act in response to racist ‘Yellow Peril’ lobbying from California politicians. In 1885 Bismarck ordered the expulsion of 40,000 Polish workers from Germany to prevent the ‘Polonization’ of Prussia. In 1897 the South African colony of Natal introduced a language test for immigrants, which barred entry to anyone who could not fill out an application form in English – a test that was specifically intended to eliminate ‘coolie’ labour from India. The ‘Natal formula’ was also introduced in Australia in order to keep out Chinese migrant workers.
