Allart Pieter van Jongestall

[6] In 1644 he represented the States of Friesland in the States-General and in 1651 at the Grote Vergadering (constitutional convention) in The Hague, which introduced the First Stadtholderless Period in the history of the Republic.

[2]: 196 In 1653 he was selected to be one of the peace commissioners to negotiate with Lord Protector Oliver Cromwell about the ending of the First Anglo-Dutch War with the Commonwealth of England, together with Paulus van de Perre, Hieronymus van Beverningh and Willem Nieupoort.

[7] Jongestall was kept out of the secret negotiations between Cromwell and Grand Pensionary Johan de Witt about the Act of Seclusion.

[2]: 197  Bordeaux, the French ambassador to the Commonwealth at the time, writes in a letter of 23 October 1654 to his colleague in the Hague, Chanut: "I must give this testimony, that during the course of his negotiation he did appear very zealous for the interest of France, and with a great correspondence.

"[9] After the Second Anglo-Dutch War, which the Republic fought with the successor state of the Commonwealth, Jongestall was again selected to be one of the peace commissioners to negotiate with king Charles II of England.

In 1673 he was appointed a member of a commission that was charged with the drafting of constitutional amendments for the States of Friesland (the Poincten Reformatoir) by the new stadtholder Hendrik Casimir II.

The Franeker professor Michiel Busschius gave his eulogy, and the poet Ernestus Baders[10] wrote an allocutio funebris: Liligerum pridem cui Regia sceptra dedereNomina pro meritis splendidiora suisFacundasque fuit mirata Britannia vocesAttonitis Tamesis dum stetit amnis aquisBredaque quem stupuit pro Libertate loquentemBelgaque quo forti Vindice liber ovat[2]: 198 Which may be translated as: Both[11] the Lys-bearing (king) whose regal sceptres[12] used to apply More splendid names for his merits;[13] And admiring Britain (that) made eloquent speeches While he stood (by) the frenzied waters of the river Thames; And Breda[14] that he has amazed speaking for freedom;
