→年幼的理查二世继位

1376年6月8日，将满46岁的“黑太子”爱德华病逝，年仅九岁的长子波尔多的理查继位。盛大的加冕典礼，万民的欢呼，一直烙印在十岁理查的脑海里。由此联想一下莎剧《理查二世》第五幕第五场，当马夫前来探视关在庞弗雷特承包地牢的理查王，对他说加冕典礼那天，布林布鲁克骑着“精心侍弄过的宝马”走过伦敦街头，接受万民欢呼时，理查王“别提心里有多难受了!”

1380年，黑死病席专下的英格兰，为凑足军饷，抵御法国。由议会宣布向全国征收人头税，导致1381年爆发由瓦特泰勒领导的英格兰历史上第一次大规模农民起义。在伦敦陷入混乱时，年仅14岁的理查二世展现了超凡的胆略迅速平息了叛乱。

→理查王与贵族的斗智斗勇

随着年龄的增长，理查二世为强化王权开始培养亲信马屁精，这就招致了一些贵族和主教的不满。随着各种矛盾的激化，英格兰开始陷入内外交困之中，最终在“美妙议会”，“残忍议会”两次议会中失去了自己的亲信，理查王失去了王权。

1397年，理查王30岁，早已成年，但他始终对自己的王权缺乏安全感。七月，理查王开始复仇，他突然下令逮捕了上诉派贵族中的三位主要人物。九月底，理查二世肃清了所有政敌，终将王权牢牢握在手心里。此刻的他也成为英格兰历史上第一个专制、苛政、残暴之君。

1398年9月16日两位贵族因“互相指认谋逆叛国”进行决斗，在双方手持矛枪骑马冲向对方时，理查王突然起身高喊”停下!停下”,私自宣布两位的流放。在这之后的情形正如莎剧中一样，1399年7月，流放在外的布林布鲁克趁理查王出兵远征爱尔兰，国内空虚，从雷文斯堡登录回到英格兰。虽然刚开始只有百人，但是没多久一大批贵族、骑士奔来，人数达到十万人，国民的拥戴让他掌控了英国兰。

→失败悲惨 囚禁处死

理查王远征失利，再上没有后援，于是布林布鲁克与理查王在弗林特城堡会面，国王宣布投降，自我囚禁在伦敦塔中，最后还是被秘密处死。

理查王终其一生都在与贵族、教廷进行斗争，虽然最终落下了身败名裂的下场，但历史始终是胜利者的笔记本，我们看到的永远都是片面的。
