March 27 (Reuters) - Police are gearing up to deal with protests in London, as leaders of the world's largest economies gather for a G20 summit in the British capital on April 2.

Here are some details of some of the recent major anti-capitalist and anti-globalisation protests at previous summits and gatherings:

Nov-Dec 1999 - SEATTLE, United States - Anti-globalisation demonstrators disrupted a World Trade Organisation meeting. Seattle declared a curfew after clashes with protesters which police dubbed "The Battle in Seattle". Around 520 were held.

Jan 2000 - DAVOS, Switzerland - Some 2,000 anti-free-trade demonstrators, denouncing the annual World Economic Forum as a "meeting of murderers", smashed car windscreens and broke windows at a McDonald's restaurant, but failed to break through police lines.

Sept 2000 - PRAGUE, Czech Republic - Protesters clashed with police near the congress centre where the International Monetary Fund and World Bank were holding their annual meetings. Police estimated some 10,000 to 12,000 protesters were involved.

April 2001 - QUEBEC CITY, Canada - Three days of clashes between police and anti-globalisation activists failed to stop a Summit of the Americas, attended by leaders from 34 countries. Most protesters were peaceful but black-clad anarchists, many of them from groups calling themselves Black Blocs, attacked the steel perimeter fence. About 400 arrests were made.

June 2001 - GOTHENBURG, Sweden - Up to 25,000 activists from dozens of anti-EU, anti-U.S. and anti-globalisation groups gathered during an EU summit, outnumbering police by up to 25 to one. Three activists were shot and injured when about 1,000 protesters rampaged through the main street.

July 2001 - GENOA, Italy - Thousands of anti-capitalist demonstrators filled Genoa during the G8 summit. One Italian protester was shot dead by police, the first death in nearly 2 years of violent anti-globalisation protests. More than 231 protesters were injured and over 280 arrested. Many complained subsequently of police brutality. In Nov. 2008 a court found 13 police officers guilty of beating protesters at the summit, but acquitted 16 others, including the most senior police officials.

June 2003 - EVIAN, France - Several hundred protesters in black hoods blocked roads and ransacked shops in the Lake Geneva area as G8 heads gathered for their annual summit.

July 2005 - GLENEAGLES, Scotland - Police arrested 91 people and seized several weapons after sometimes violent confrontations around the summit. Police the next day threw a security cordon around the protestors campsite in Stirling, 32 km (20 miles) south of Gleneagles.

July 2006 - ST PETERSBURG, Russia - Russian police detained 22 anti-globalisation protesters who briefly blocked a road in St Petersburg holding up posters with the slogan "No G8!".

June 2007 - HEILIGENDAMM, Germany - Police stopped three Greenpeace speedboats after a chase in Baltic waters close to the G8 summit venue. A banner saying "G8 act now" had been displayed. Around 30,000 demonstrators also succeeded in evading police controls and entering a restricted zone set up for the summit around the venue, 250 km (150 miles) north of Berlin. They blocked land routes into the village for three days before leaving at the end of the summit. July 2008 - HOKKAIDO - Protesters tried to push through police lines to get closer to the summit in northern Japan, but were easily turned back by police. 21,000 officers contained protests with only a few scuffles and a handful of arrests.
