The Protestants, alarmed at the usage they had met with at the former Diet, had secretly proposed among themselves to form a general union or confederacy, for preventing that ruin which they saw, unless some speedy remedies were applied, would be inevitable.  The Elector of Saxony, the head of the Protestants, a vigorous and politic prince, was the first that moved it; and the Landgrave of Hesse, a zealous and gallant prince, being consulted with, it rested a great while between those two, no method being found practicable to bring it to pass, the emperor being so powerful in all parts, that they foresaw the petty princes would not dare to negotiate an affair of such a nature, being surrounded with the Imperial forces, who by their two generals, Wallenstein and Tilly, kept them in continual subjection and terror.

This dilemma had like to have stifled the thoughts of the union as a thing impracticable, when one Seigensius, a Lutheran minister, a person of great abilities, and one whom the Elector of Saxony made great use of in matters of policy as well as religion, contrived for them this excellent expedient.
