It has been argued that Offa's authority was recognised early in his reign by local kings in western Sussex, but that eastern Sussex (the area around Hastings) submitted to him less readily.
Telah diperdebatkan bahwa wewenang Offa diakui di masa awal pemerintahannya dengan raja-raja lokal di Sussex barat, namun Sussex timur (wilayah di sekitar Hastings) menyerah kepadanya setengah hati.
