Context: Glass has the ability to refract, reflect, and transmit light following geometrical optics, without scattering it. It is used in the manufacture of lenses and windows. Common glass has a refraction index around 1.5. This may be modified by adding low-density materials such as boron, which lowers the index of refraction (see crown glass), or increased (to as much as 1.8) with high-density materials such as (classically) lead oxide (see flint glass and lead glass), or in modern uses, less toxic oxides of zirconium, titanium, or barium. These high-index glasses (inaccurately known as "crystal" when used in glass vessels) cause more chromatic dispersion of light, and are prized for their diamond-like optical properties.

input: Please answer the following: Extract the answer to the question from the following context. Question: What began on the 20th year of the 19th century? Context: Ferdinand refused and went to Valencia instead of Madrid. Here, on 17 April, General Elio invited the King to reclaim his absolute rights and put his troops at the King's disposition. The king abolished the Constitution of 1812. He followed this act by dissolving the two chambers of the Spanish Parliament on 10 May. Thus began six years (1814–1820) of absolutist rule, but the constitution was reinstated during the Trienio Liberal, a period of three years of liberal government in Spain from 1820–1823.
