Book review: The Holy Roman Empire – Europe from Charlemagne to UKIP
Peter Wilson encourages the reader to reassess the worth of the empire at the heart of Europe, but his book’s depth, length, and focus on ideas rather than individuals – demands a lot of stamina

When the Holy Roman Emperor Charles V besieged Metz in 1522 the city taunted him with a banner emblazoned with the imperial eagle chained between two pillars. These represented the ancient pillars of Hercules, the border of the known world at the straits of Gibraltar, where a notice warned “Non plus ultra” – “no further beyond”.
Charles had adopted the motto “Plus ultra” to emphasise his imperial power, so underneath the restrained eagle, the defenders of Metz wrote “Non plus Metas”, meaning both “not beyond Metz” and “not beyond the boundaries”.
