After the Civil War began, Governor Zebulon Baird Vance ordered the construction of breastworks around the city as protection from Union troops. During General Sherman's Carolinas Campaign, Raleigh was captured by Union cavalry under the command of General Hugh Judson Kilpatrick on April 13, 1865. As the Confederate cavalry retreated west, the Union soldiers followed, leading to the nearby Battle of Morrisville. The city was spared significant destruction during the War, but due to the economic problems of the post-war period and Reconstruction, with a state economy based on agriculture, it grew little over the next several decades.
What did the governor order constructed?
breastworks

In the 1970s, job losses due to industrial restructuring caused New York City to suffer from economic problems and rising crime rates. While a resurgence in the financial industry greatly improved the city's economic health in the 1980s, New York's crime rate continued to increase through that decade and into the beginning of the 1990s. By the mid 1990s, crime rates started to drop dramatically due to revised police strategies, improving economic opportunities, gentrification, and new residents, both American transplants and new immigrants from Asia and Latin America. Important new sectors, such as Silicon Alley, emerged in the city's economy. New York's population reached all-time highs in the 2000 Census and then again in the 2010 Census.
In what year did the population of New York reach an all-time high for the second time in this period?
2010
