Answer:
The significance of the Battles of Lexington and Concord was that they were the first battles of the American Revolutionary War.
Explanation:
The Battle of Lexington and Concord was fought on April 19, 1775 in Middlesex County, in the Massachusetts Bay Province, particularly near the villages of Lexington and Concord. The clash saw a contingent of British troops committed, departed from Boston under the command of Lieutenant Colonel Francis Smith and then reinforced by a second detachment led by Lieutenant General Hugh Percy, and a group of colonial militia, including the minutemen, led first by the Captain John Parker and then by Brigadier General William Heath.
The battle, which ended with the retreat of the British troops and the victory of the colonial units, marked the official beginning of the American War of Independence between Great Britain and the Thirteen colonies.
