Liao Dynasty
By the mid 11th century, the Khitan had lost their morale and started adopting a defensive attitude towards their neighbors.
11世纪中期，契丹丢失了他们的士气，对于他们的邻国开始采取一种防备的态度。
This was in part due to the influence of Buddhism and the fad that they had absorbed much of Chinese culture, which had a negative effect on their manners.
这在一部分上缘于他们受到了佛教和过多的中国文化的影响，因此对他们自己的行为产生了负面的作用。Around the 12th century, the empire's slow decline sped up as a result of succession problems, natural disasters, and the positive progress of the Jurchen in the north east.
12世纪左右，由于一系列问题、自然灾害以及东北部女真族的积极发展，辽朝的缓慢衰落加快了。More pressure was put on the Khitan when the Jurchen and Song made an alliance against them and in 1124----1125, the Khitan Empire collapsed.
当女真和宋朝结成联军展开攻势后，契丹的压力更大了，1124年到1125年间，契丹帝国灭亡了。
