At the same time that Western Europeans joined an expedition against the Muslims in the Middle East, the struggle against the Moors in Spain continued with renewed vigor and campaigns were mounted against the Wends in Pomerania and Lusatia.

1163 During Emperor Frederick I Barbarossa's third visit to Italy, a number of Northern Italian towns formed a military alliance to resist his authority.

Among its first acts was the signing of a treaty with the League of Verona (founded in 1163). Emperor Frederick I Barbarossa ordered his troops to occupy Rome and thus tried to prevent the pope from helping the Northern Italian cities.
1168 The fortified town of Alessandria was founded in the Northern Italian region of Piemonte and baptized in honor of Pope Alexander III, who supported the Northern Italian towns in their struggle against Emperor Frederick I Barbarossa.

1175 Venice secured the alliance of the Sicilian Normans in its war with the Byzantine Empire.
1176 On May 29, the army of Emperor Frederick I Barbarossa was defeated in the Battle at Legnano by the army of the League of Lombardy, the alliance of Northern Italian towns led by Milan.
