Explica como es la relacion de poder en el sistema feudal
SVETLANKA909090 [29]
Feudalismo es la denominación del sistema político predominante en la Europa Occidental de los siglos centrales de la Edad Media (entre los siglos IX al XV, aunque no hay acuerdo entre los historiadores sobre su comienzo y su duración, y esta varía según la región),[1]​ y en la Europa Oriental durante la Edad Moderna, caracterizado por la descentralización del poder político; al basarse en la difusión del poder desde la cúspide (donde en teoría se encontraban el emperador o los reyes) hacia la base donde el poder local se ejercía de forma efectiva con gran autonomía o independencia por una aristocracia, llamada nobleza, cuyos títulos derivaban de gobernadores del imperio carolingio (duques, marqueses, condes) o tenían otro origen (barones, caballeros, etc.).

El término «feudalismo» también se utiliza historiográficamente para denominar las formaciones sociales históricas caracterizadas por el modo de producción que el materialismo histórico (la historiografía marxista) denomina feudal.[2]​

Como formación económico-social, el feudalismo se inició en la Antigüedad tardía con la transición del modo de producción esclavista al feudal, a partir de la crisis del siglo III y, sobre todo, con la disolución del Imperio romano de Occidente (siglo V) y la formación de los reinos germánicos y el Imperio carolingio (siglos VIII y IX).

Fundamentado en distintas tradiciones jurídicas (tanto del derecho romano como del derecho germánico –relaciones de clientela, séquito y vasallaje–), el feudalismo respondió a la inseguridad e inestabilidad de la época de las invasiones que se fueron sucediendo durante siglos (pueblos germánicos, eslavos, magiares, musulmanes, vikingos). Ante la incapacidad de las instituciones estatales, muy lejanas, la única seguridad provenía de las autoridades locales, nobles laicos o eclesiásticos, que controlaban castillos o monasterios fortificados en entornos rurales, convertidos en los nuevos centros de poder ante la decadencia de las ciudades.

Desde el punto de vista institucionalista, el feudalismo fue el conjunto de instituciones creadas en torno a una relación muy específica: la que se establecía entre un hombre libre (el vasallo), que recibía la concesión de un bien (el feudo) por parte de otro hombre libre (el señor), ante el que se encomendaba en una ceremonia codificada (el homenaje) que representaba el establecimiento de un contrato sinalagmático (de obligaciones recíprocas).[3]​ Esta serie de obligaciones recíprocas, militares y legales, establecidas entre la nobleza guerrera; giraba en torno a tres conceptos clave: señor, vasallo y feudo. Entre señor y vasallo se establecían las relaciones de vasallaje, esencialmente políticas. En el feudo, entendido como unidad socio-económica o de producción, se establecían relaciones de muy distinta naturaleza, entre el señor y los siervos; que desde la historiografía marxista se explican como resultado de una coerción extraeconómica por la que el señor extraía el excedente productivo al campesino. La forma más evidente de renta feudal era la realización por los siervos de prestaciones de trabajo (corveas o sernas); con lo que el espacio físico del feudo se dividía entre la reserva señorial o reserva dominical (donde se concentraba la producción del excedente) y los mansos (donde se concentraba la producción imprescindible para la reproducción de la fuerza de trabajo campesina). En otras formas, los siervos se obligaban a distintos tipos de pago; como una parte de la cosecha o un pago fijo, que podía realizarse en especie o en moneda (forma poco usual hasta el final de la Edad Media, dado que en siglos anteriores la circulación monetaria, y de hecho todo tipo de intercambios, se reducían al mínimo), a los que se añadían todo tipo de derechos y monopolios señoriales.[4]​tal vez ayuda :).

Which three actions or events were most critical in the social economic and political transformation of china into a global powe
djyliett [7]

Answer:

China overtakes the United States and is already in 2014 the world's leading economic power, according to the latest data from the International Monetary Fund (IMF). A milestone that comes five years earlier than expected, because until now those who lost from the IMF had changed this historic change until 2019.

Specifically, China's GDP in 2013 reached 16.15 trillion dollars and that of the United States, which has been the first power on the planet since it surpassed the United Kingdom in 1872, exceeded that level to climb to 16.77 million of dollars. A year later, the scenario changes: China adds 17.632 trillion and the United States, 17.416 trillion, in a new world order that will be maintained for at least the next five years, according to the IMF.

And is that the difference between China and the US USA It will be expanded in favor of the first until 2019, the last year for which the Fund prepares forecasts (see attached table). In that exercise, the Chinese GDP will be 26.9 trillion dollars and that of the United States, 22.1 trillion.

It is the result of the solid growth rates of the Asian tiger, which will reach 7.4% this year and 7.1% in 2015. More long-term, China, which faces the challenge of achieving a "soft landing" In a transition towards a more sustainable economy and dependent on domestic demand, it will grow 6.8% in 2016, 6.6% a year later, 6.4% in 2018 and 6.3% in 2019.

Meanwhile, the US, which bears the weight of budgetary imbalances and with a slow advance in the labor market, will accelerate 2.2% in 2014 and 3.1% in 2015. Already in 2016, the rate will be 3%, to go to 2.9% in 2017 and 2.7% in 2018. The Fund series closes in 2019, when this slowdown is confirmed at 2.6%. However, the United States is still much richer than China, where per capita income accounts for only a fifth of Americans.

This measurement is carried out in purchasing power parity, the most rigorous, since it is not subject to exchange rate volatilities, as it does in the calculation based on the volume of GDP in current dollars. In the latter case, none of the international organizations predicts a similar relief.

What does occur in one measure or another is a sharp decline in Spain. The country, which in 2007 boasted of playing in the economic Champions League, goes from the twelfth place before the crisis to the seventeenth. Thus, it loses 5 positions in the ranking due to purchasing power parity, being overtaken by Canada, Indonesia, Korea, Turkey and Saudi Arabia.

In the current dollar ranking, the weight loss is much more evident, as it gives up seven places. From eighth place in 2007 it falls to fourteenth in 2019, surpassed by India, Brazil, Russia, Canada, Korea, Australia and Mexico.

Explanation:

In 1946, the world began to be governed by the military policies and actions undertaken and directed by Washington and Moscow, which formed a new international order led by a formal dimension, represented by the United Nations, and an informal one, embodied in The War. Cold The latter, which in fact modeled and gave reality to the international order and enabled a specific geopolitics, ended in 1991. European states became a second-order power, retaining historical credentials, but few levers of real power.

By 1992, many observers identified Washington as the great global power. Many spoke of the United States as a hyperpower, something that really had only been from 1945 to 1949, when it had the most advanced form of military destruction, the nuclear bomb, alone.

The People's Republic of China has rapidly become, without contemplation or pause –since the government reforms introduced by Deng Xiaoping, from 1978–, a growing economic power. It was industrially reformed, with very evident supports in industry and in the scientific development that emerged from the 1979 university reform, which had as its central point its de-ideologization and the full introduction of the main world scientific and technological developments.
