繪本簡介

For five centuries starting around 27 BC, the leaders of the Roman Empire ruled successfully over large areas of Europe. Eventually, the empire became so vast that it had to be divided between two emperors. This division considerably reduced the power of the empire, which lost control of its borders, leaving them open to attack from invaders. Taking advantage of the weakness and lack of strong leadership, the Visigoths attacked and destroyed the city of Rome. After this devastating blow came an even greater challenge to the empire: A ferocious leader named Attila the Hun attacked the Roman Empire from the east and the west. To save the empire, Aetius, a great Roman general, persuaded several tribes in the empire to join forces and form an army to fight Attila. This huge army defeated Attila at the monumental Battle of Chalons. Photographs, maps, and illustrations support the text..

從公元前 27 年左右開始的五個世紀(jì)里，羅馬帝國的領(lǐng)導(dǎo)人成功地統(tǒng)治了歐洲的大片地區(qū)。 最終，帝國變得如此龐大，以至于它不得不被兩個皇帝瓜分。 這種分裂大大削弱了帝國的力量，失去了對邊界的控制，使它們?nèi)菀资艿饺肭终叩墓簟?西哥特人利用軟弱和缺乏強(qiáng)有力的領(lǐng)導(dǎo)，襲擊并摧毀了羅馬城。 在這次毀滅性的打擊之后，帝國面臨更大的挑戰(zhàn)：一位名叫阿提拉的兇猛的匈奴人從東西方進(jìn)攻羅馬帝國。 為了拯救帝國，羅馬大將埃提烏斯說服了帝國的幾個部落聯(lián)合起來組成軍隊對抗阿提拉。 這支龐大的軍隊在不朽的沙隆戰(zhàn)役中擊敗了阿提拉。 照片、地圖和插圖支持文本。
