The Titanic sank because it hit an iceberg on the night of Ap 
ril 14, 1912, during its maiden voyage from Southampton, England to New York City. The ship was not able to stay afloat after the collision, which caused it to take on water and eventually sink.
While the Titanic did have lifeboats on board, there were not enough of them to accommodate all of the passengers and crew. There were a total of 20 lifeboats, which could hold a total of about 1,178 people, but the Titanic was carrying more than 2,200 passengers and crew when it sank. As a result, many people were left stranded on the sinking ship and were unable to escape.
It's also worth noting that the lifeboats on the Titanic were not equipped with motors, so they could not travel far from the sinking ship. This made it difficult for them to rescue people who were in the water, as the lifeboats were not able to move quickly or maneuver around the debris. Overall, the lack of sufficient lifeboats and their limited capabilities played a significant role in the tragic loss of life that occurred when the Titanic sank.
