102 A Short History of the Middle East Its isolation in the closed environment of the Nile Valley1 and its debilitation by endemic disease; and he liad no instrument for the execution of his plans comparable for energy, devotion, training, powers of leadership, and ruthlessness towards opposition or incompetence, with the Communist party in the U.S.S.R.2 Another instructive comparison Is with the Westernization of the Japanese economy in the second half of the nineteenth century. Here again the initial advantages were all with the Japanese since, although their economic and social system was already being undermined by degenerative processes, Japan even in her isolation was a far more healthy organism than decayed and depopulated Egypt. The Emperor was an institution with divine attributes that could be used as a focus for the absolute loyalty and fanatical devo- tion of a people who had learnt by tradition to regard these as the supreme virtues of their race. The ruling-class, while enjoying prestige and self-confidence, was not rigidly separated from the rest of the population, but provided opportunities for men of talent to rise into its ranks. In every class there was a capacity for co-operation and organized effort which was in part the product of a long experience of group action in the family, the clan, and the guild.'3 In the light of these comparisons, so unfavourable to the ex- hausted condition of Egypt at the accession of Mohammed Ali, the cause for surprise is not that he failed to achieve his plans for material re-organization, but that he was able to effect what must have seemed impossible fifty years before, the lifting of Egypt out of the morass in which centuries of misrule were smothering her. He permanently increased the agricultural productivity of the country by the introduction of perennial irrigation, though at the cost of thereby lowering the natural fertility of the soil, formerly enriched annually by the Nile mud but now requiring the addition of fertilizers. It is some index of the improved agricultural pro- ductivity that, after centuries in which the population of Egypt had declined to perhaps only one-third or one-quarter of its ancient maximum, it should, according to estimates, have Increased by some 75 per cent, in one generation between 1821 and 1847, not- 1 This factor is well brought out by D.
