A now-forgotten 18th-century masque about this man popularized the song “Rule, Britannia!” Modern scholars have challenged the originality of a type of defensive structure supposedly invented by (20[1])this ruler (20[1])called (0[1])a burh. (20[6])This (20[2])monarch (20[1])baptized (20[1])the enemy commander after successfully (20[1])besieging (20[1])the fort of Chippenham. (0[1])This monarch’s (20[1])mania (20[1])for books is related in a “Life” (0[1])by (*) Asser. A law code (0[1])named for this monarch incorporated an earlier code from Offa of Mercia (10[1])and shares textual elements with the Treaty (0[1])of Wedmore he negotiated. (0[1])This (10[1])monarch defeated Guthrum (10[1])the Old, (10[1])a Viking ruler, at the Battle of (10[1])Edington. For 10 points, name this “Great” king of Wessex. (10[3]0[2])■END■ (10[7]0[2])
