This worksheet allows students to use a short powerful primary source document written by President Lincoln to the workers of Manchester, England. This primary source helps students to learn about the global economic impact of the American Civil War. The letter written by Lincoln is also great at explaining why Great Britain stayed out of the American Civil War, but also why there was pressure for Great Britain to enter into the American Civil War. The worksheet allows students to read and highlight a short two page letter that Lincoln is writing to the working class people of Manchester, England whom have been impacted by the lack of cotton imports from the United States. The worksheet includes twelve questions and has an answer key for the teacher. The reading is very engaging for students. The worksheet will take most student 15 to 20 minutes to finish depending on age, but it can take an entire class period if the teacher decides to go through the letter with the class and have discussions about the questions.
