Paul writes 1 and 2 Thessalonians from Corinth
1 Thessalonians 1:1; 3:1–6; 2 Thessalonians 1:1; 2:1–3
Forced out of Thessalonica after only a few weeks, Paul wrote from Corinth to encourage the young church under persecution, to answer their questions about believers who had died, and to calm fears that the day of the Lord had already come.
Always rejoice. Pray without ceasing. In everything give thanks, for this is the will of God in Christ Jesus toward you.
1 Thessalonians 5:16–18 (World English Bible)
Timothy had brought good news of their faith and love (1 Thessalonians 3:6). These are probably Paul's earliest surviving letters after Galatians, written with Silas (Silvanus) and Timothy.

About AD 50–51, during Paul's stay in Corinth; the second letter a few months after the first. Ussher dates 1 Thessalonians to AD 54. The date is an estimate; Scripture doesn't say when the book was written.
