Christopher Seider (or Snider) (1758—1770) was a British colonist killed in the political strife that became the American Revolutionary War. He was 11 years old when he was shot and killed by loyalist Ebenezer Richardson in Boston on February 22, 1770. His funeral became a major political event, with his death heightening tensions that erupted into the Boston Massacre on March 5, 1770.
Seider was born in 1758, the son of poor German immigrants. On February 22, 1770, he joined a crowd outside the house of Ebenezer Richardson in the North End. Richardson was a customs service employee who had tried to disperse a protest in front of the shop of a Loyalist, Theophilus Lillie. The crowd threw stones that broke Richardson's windows and struck his wife. Richardson fired a gun into the crowd and wounded Seider in the arm and the chest. The boy died that evening.
Seider's killing and large public funeral fueled public outrage, which reached a peak in the Boston Massacre 11 days later. Richardson was convicted of murder that spring but received a royal pardon and a new position within the customs service on the grounds that he had acted in self-defense. That became a major American grievance against the British government.
Christopher's death, his funeral, and the subsequent Boston Massacre are featured in the 2015 television miniseries Sons of Liberty and season 2 of the 2016 television docuseries Legends & Lies: The Patriots.
