Of Spain to the Conventa dos Jeronymos in Lisbon, many Portuguese refused to credit his death.
The first authentic pacta conventa made between the Polish nobility and the Crown dates from the compact of Kassa (September 17, 137 4), when Louis of Hungary agreed to exempt the szlachta from all taxation, except two Polish groschen per hide of land, and to compensate them for the expenses of all military service rendered beyond the confines of the realm.
He was bound by the pacta conventa which he signed on his accession to maintain a fleet on the Baltic. He proposed to do so by levying tolls on all imports and exports passing through the Prussian ports which had been regained by the truce of Stumdorf.
Simultaneously Wladislaus contracted an offensive and defensive alliance with Venice against the Porte, a treaty directly contrary indeed to the pacta conventa he had sworn to observe, but excusable in the desperate circumstances.
