Unusually for a Holstein jumping sire, Capitol carries no Cor de la Bryère blood, but his pedigree  is richly endowed with the heritage of two great Thoroughbred descendants of the Bay Ronald line - Cottage Son xx and Manometer xx, he also carried a double cross of the influential Anglo-Arab stallion, Ramzes.
Capitol also sired Cassini 1 and Cassini 2, Campione (and full brother, Cathleen, ridden by Meredith Michaels Beerbaum), Calato Z, Curtis, and Cliquot. With an index of 182 he headed the FEI young jumping stallion ratings. Capitol’s grand dam, Retina, was the champion of the Hamburg Jumping Derby ridden by Fritz Thiedemann.

His dam, Folia, showed great jumping potential herself, and produced the licensed stallions Latus I and II, as well as the two Capitols, and famous daughters Kausa, Lexington (eventing) and U-Capitola (dam of Lord Capitol).

Folia’s dam, Vase, was a full sister to Romanus who competed with success with Hans Günter Winkler.

The dam’s sire, Calando I stood at several breeding stations in Holstein before pursuing a performance career that culminated in a German Championship with Karsten Huck. After jumping successfully in Luxembourg, Calando I returned to Holsteinf for Stud duites and eventual retirement.
