after the second world war, the gelderlander and groninger were replaced by tractors and cars, and horses began to become a luxury rather than a necessity. as early as the 1950s, stallions like the french-bred "l'invasion" and holsteiner "normann" were imported to encourage a change in the type of dutch horses, followed soon after by the holsteiner "amor" and hanoverian "eclatant". the carriage-pulling foundation stock contributed their active, powerful front ends and gentle dispositions to the dutch warmblood.
