Prince Harry was giving evidence against Mirror Group Newspapers (MGN) over illegal newsgathering claims, including phone hacking.
He was choked-up as he finished giving evidence for a second day, and said it had been "a lot".
MGN denies it used illegal methods to gather stories about the prince.
At London's High Court, the prince explained he started discussions about possible legal action after a chance-meeting in France in 2018 with David Sherborne, now his barrister.
The prince said before then he had no concerns over any particular newspaper stories due to unlawful activity because it "was all contained in the Palace".
