The position of the burgomaster was the most striking of all, and was, in fact, that of a Roman dictator of old, or resembling the Italian tyrannies of the Visconti or Medici. Elected for life, vested with absolute power, the burgomaster was responsible to none, whilst to him fealty was to be sworn by all on pain of losing the rights of citizenship. The idol of the people to whom he had granted political power, Brun was regarded as the true pilot and saviour in stormy times. The fallen councillors brooded revenge, and being banished the town, resorted to Rapperswyl, the Zurich _extra muros_, and at the other end of the lake. There they made _chose commune_ with Count John of that place, who was desirous of evading payment of the debts he had contracted in Zurich. Feuds and encounters followed, and John was slain in battle in 1337. The emperor tried to restore peace, but the exiled councillors were bent on bringing back the old state of things, and on regaining their seats. They plotted against Brun's life, and those of his associates, and fixed upon the 23rd of February, 1350, for making an attack by night on the city, with the intention of seizing it by a single _coup-de-main_. They relied on the help of sympathisers within the town. The burgomaster, being apprized of the plot, summoned his faithful burghers to arms by the ringing of the tocsin. A bloody hand-to-hand fight in the streets took place, thence called the _Zurcher Mordnacht_. The conspiracy was crushed by the majority, and Count John of Rapperswyl, son of the above-mentioned count, was thrown into the tower of Wellenberg, a famous state prison. There he passed his time in the composition of _Minnelieder_.
