Glaniodd y Windrush yn dilyn pasio Deddf Cenedligrwydd Prydeinig 1948, ar adeg pan oedd Prydain yn parhau i geisio dod dros holl ddinistr yr Ail Rhyfel Byd. Ar yr adeg honno, roedd cydnabyddiaeth fod ar Brydain angen asedau a chryfderau dinasyddion y Gymanwlad i helpu i ail-adeiladu ein cymdeithas. Rhoddodd Deddf Cenedligrwydd Prydeinig wahoddiad clir i unigolion ddod i ymgartrefu ym Mhrydain. Mae Llywodraeth Cymru'n parhau i anrhydeddu'r gwahoddiad hwnnw heddiw.
The Empire Windrush landing followed the passing of the British Nationality Act 1948, at a time when Britain was struggling to recover from the devastation of the Second World War. It was recognised then that Britain needed the assets and strengths of Commonwealth citizens to help rebuild our society. The British Nationality Act presented a clear invitation for individuals to come to Britain to make a new home. The Welsh Government continues to honour that invitation today.
