The Republic of Liberia, beginning as a settlement of the American Colonization Society (ACS), declared its independence on July 26, 1847. The United States did not recognize Liberia's independence until during the American Civil War on February 5, 1862. Between January 7, 1822 and the American Civil War, more than 15,000 freed and free-born Black Americans from United States and 3,198 Afro-Caribbeans relocated to the settlement. The Black American settlers carried their culture with them to Liberia. The Liberian constitution and flag were modeled after the United States. In January 3, 1848 Joseph Jenkins Roberts, a wealthy free-born Black American from Virginia who settled in Liberia, was elected as Liberia's first president after the people proclaimed independence.

In the 20th century, new types of glass such as laminated glass, reinforced glass and glass bricks have increased the use of glass as a building material and resulted in new applications of glass. Multi-storey buildings are frequently constructed with curtain walls made almost entirely of glass. Similarly, laminated glass has been widely applied to vehicles for windscreens. While glass containers have always been used for storage and are valued for their hygienic properties, glass has been utilized increasingly in industry. Optical glass for spectacles has been used since the late Middle Ages. The production of lenses has become increasingly proficient, aiding astronomers as well as having other application in medicine and science. Glass is also employed as the aperture cover in many solar energy systems.
What type of scientists rely on glass for distant observations?
astronomers

Geographically, the empire was divided into several provinces, the borders of which changed numerous times during the Umayyad reign. Each province had a governor appointed by the khalifah. The governor was in charge of the religious officials, army leaders, police, and civil administrators in his province. Local expenses were paid for by taxes coming from that province, with the remainder each year being sent to the central government in Damascus. As the central power of the Umayyad rulers waned in the later years of the dynasty, some governors neglected to send the extra tax revenue to Damascus and created great personal fortunes.
Along with army leaders, police and civil administration, what did the governor control in his province?
