In 1845 the fire insurance company the Assurantie Maatschappij tegen Brandschade de Nederlanden van 1845 (Fire insurance company of the Netherlands established 1845) was founded and grew to be the first insurance company with branches outside the Netherlands, of which it had 139 the world over by 1900. It later changed its name to "De Nederlanden van 1845". Two decades later in 1863 the life insurance company Nationale Levensverzekerings Bank (National Life Insurance Bank) was founded in Rotterdam. These two insurance companies would make multiple acquisitions before merging to form the combined insurance company the Nationale-Nederlanden in 1963. The combined insurance company would expand significantly during the 1970s and 1980s
