Were all of plays performed during his lifetime?

William Shakespeare lived from 1564 to 1616. During his lifetime, many of his plays were performed by acting companies such as the Lord Chamberlain's Men, later known as the King's Men. However, it is believed that not all of his plays were performed during his lifetime. Some of his plays may have been performed posthumously, while others may have been lost or never produced. There is some debate among scholars about which of Shakespeare's plays were performed during his lifetime and which were not.
