In 1819 Beethoven began work on the Diabelli Variations and the Missa Solemnis, composing over the next few years piano sonatas and bagatelles to satisfy the demands of publishers and the need for income. He was ill again for an extended time in 1821 and completed the Missa in 1823, three years after its original due date. Around 1822 his brother Johann began to assist him in his business affairs, including him lending him money against ownership of some of his compositions.
On 15 February 1819, Bolívar was able to open the Venezuelan Second National Congress in Angostura, in which he was elected president and Francisco Antonio Zea was elected vice president. Bolívar then decided that he would first fight for the independence of New Granada, to gain resources of the vice royalty, intending later to consolidate the independence of Venezuela.
While the campaign was successful, the power of the Saudis was not broken. They continued to harass Ottoman and Egyptian forces from the central Nejd region of the Peninsula. Consequently, Muhammad Ali dispatched another of his sons, Ibrahim, at the head of another army to finally rout the Saudis. Then, the Saudis were crushed and most of the Saudi family was captured. The family leader, Abdullah ibn Saud, was sent to Istanbul and executed.
The campaign for the independence of New Granada, which included the crossing of the Andes mountain range, one of history's military feats, was consolidated with the victory at the Battle of Boyacá on 7 August 1819. The Battle of Boyacá (1819), was the decisive battle that ensured the success of Bolívar's campaign to liberate New Granada. The battle of Boyaca is considered the beginning of the independence of the North of South America, and is considered important because it led to the victories of the battle of Carabobo in Venezuela, Pichincha in Ecuador, and Junín and Ayacucho in Peru.
Bolívar returned to Angostura, when congress passed a law forming a greater Republic of Colombia on 17 December, making Bolívar president and Zea vice president, with Francisco de Paula Santander vice president on the New Granada side, and Juan Germán Roscio vice president on the Venezuela side.
