Truth learned that her son Peter, then five years old, had been sold illegally by Dumont to an owner in Alabama. With the help of the Van Wagenens, she took the issue to court and in 1828, after months of legal proceedings, she got back her son, who had been abused by those who were enslaving him. Truth became one of the first black women to go to court against a white man and win the case.
Bolívar had great difficulties maintaining control of the vast Gran Colombia. In 1826, internal divisions sparked dissent throughout the nation, and regional uprisings erupted in Venezuela. The new South American union had revealed its fragility and appeared to be on the verge of collapse. To preserve the union, an amnesty was declared and an arrangement was reached with the Venezuelan rebels, but this increased the political dissent in neighboring New Granada. In an attempt to keep the nation together as a single entity, Bolívar called for a constitutional convention at Ocaña in March 1828.
This move was considered controversial in New Granada and was one of the reasons for the deliberations, which met from 9 April to 10 June 1828. The convention almost ended up drafting a document which would have implemented a radically federalist form of government, which would have greatly reduced the powers of a central administration. The federalist faction was able to command a majority for the draft of a new constitution which has definite federal characteristics despite its ostensibly centralist outline. Unhappy with what would be the ensuing result, pro-Bolívar delegates withdrew from the convention, leaving it moribund.
Beethoven then turned to write the string quartets for Golitsin. Of these "Late Quartets", Beethoven's favorite was the Fourteenth Quartet, op. 131 in C♯ minor, which he rated as his most perfect single work. The last musical wish of Schubert was to hear the Op. 131 quartet, which he did on 14 November 1828, five days before his death.
