Context: European colonialism in the Sahara began in the 19th century. France conquered the regency of Algiers from the Ottomans in 1830, and French rule spread south from Algeria and eastwards from Senegal into the upper Niger to include present-day Algeria, Chad, Mali then French Sudan including Timbuktu, Mauritania, Morocco (1912), Niger, and Tunisia (1881). By the beginning of the 20th century, the trans-Saharan trade had clearly declined because goods were moved through more modern and efficient means, such as airplanes, rather than across the desert.

Context: A second neoclassic wave, more severe, more studied and more consciously archaeological, is associated with the height of the Napoleonic Empire. In France, the first phase of neoclassicism was expressed in the "Louis XVI style", and the second in the styles called "Directoire" or Empire. The Rococo style remained popular in Italy until the Napoleonic regimes brought the new archaeological classicism, which was embraced as a political statement by young, progressive, urban Italians with republican leanings.[according to whom?]

input: Please answer the following: Extract the answer to the question from the following context. Question: Who is the author of this book? Context: The theme of racial injustice appears symbolically in the novel as well. For example, Atticus must shoot a rabid dog, even though it is not his job to do so. Carolyn Jones argues that the dog represents prejudice within the town of Maycomb, and Atticus, who waits on a deserted street to shoot the dog, must fight against the town's racism without help from other white citizens. He is also alone when he faces a group intending to lynch Tom Robinson and once more in the courthouse during Tom's trial. Lee even uses dreamlike imagery from the mad dog incident to describe some of the courtroom scenes. Jones writes, "[t]he real mad dog in Maycomb is the racism that denies the humanity of Tom Robinson .... When Atticus makes his summation to the jury, he literally bares himself to the jury's and the town's anger."

Context: Similarly, the federal constitutional initiative allows citizens to put a constitutional amendment to a national vote, if 100,000 voters sign the proposed amendment within 18 months.[note 8] Parliament can supplement the proposed amendment with a counter-proposal, and then voters must indicate a preference on the ballot in case both proposals are accepted. Constitutional amendments, whether introduced by initiative or in Parliament, must be accepted by a double majority of the national popular vote and the cantonal popular votes.[note 9]
