+# WPT conformance-checker tests
+
+The files in this part of the tree are not browser tests; they're documents
+intended for testing the behavior of conformance checkers (e.g., validator.nu
+and the W3C Nu Markup Validator).
+
+To update the generated tests, run `wpt update-built --include conformance-checkers`.
+
+TK: We should have here some details about the contents of the existing
+subdirectories in this tree...
+
+Curious committers should see the makefile.

Слова эти, однако, на деле не вполне оправдались. Мягкая, общительная натура царя нуждалась в советчике и друге. Таким «особенным», особенно любимым другом стал Никон. Будучи в то время митрополитом в <a href="/wiki/%D0%9D%D0%BE%D0%B2%D0%B3%D0%BE%D1%80%D0%BE%D0%B4" class="mw-redirect" title="Новгород">Новгороде</a>, где со свойственной ему энергией он в марте 1650 года усмирял мятежников, Никон овладел доверием царским, посвящён был в патриархи (<abbr title="по юлианскому календарю">25&#160;июля</abbr>&#160;(<a href="/wiki/4_%D0%B0%D0%B2%D0%B3%D1%83%D1%81%D1%82%D0%B0" title="4 августа"><span title="по григорианскому календарю">4&#160;августа</span></a>)&#160;<a href="/wiki/1652_%D0%B3%D0%BE%D0%B4" title="1652 год">1652</a> года и стал оказывать прямое влияние на дела государственные. Из числа последних особенное внимание правительства привлекали внешние отношения.</p>
+<p>Патриарху Никону было поручено провести <a href="/wiki/%D0%A6%D0%B5%D1%80%D0%BA%D0%BE%D0%B2%D0%BD%D0%B0%D1%8F_%D1%80%D0%B5%D1%84%D0%BE%D1%80%D0%BC%D0%B0_%D0%BF%D0%B0%D1%82%D1%80%D0%B8%D0%B0%D1%80%D1%85%D0%B0_%D0%9D%D0%B8%D0%BA%D0%BE%D0%BD%D0%B0" class="mw-redirect" title="Церковная реформа патриарха Никона">церковную реформу</a>.

Было введено крещение тремя пальцами, поясные поклоны вместо земных, исправлены по греческим образцам иконы и церковные книги.

+<p>Новый патриарх был человеком своенравным, волевым, во многом фанатичным. Получив необъятную власть над верующими, он вскоре выступил с идеей первенства церковной власти и предложил Алексею Михайловичу разделить с ним власть. Однако царь не пожелал долго терпеть патриарха. Он перестал ходить на патриаршие богослужения в <a href="/wiki/%D0%A3%D1%81%D0%BF%D0%B5%D0%BD%D1%81%D0%BA%D0%B8%D0%B9_%D1%81%D0%BE%D0%B1%D0%BE%D1%80_(%D0%9C%D0%BE%D1%81%D0%BA%D0%B2%D0%B0)" title="Успенский собор (Москва)">Успенском соборе</a>, приглашать Никона на государственные приёмы. Это было серьёзным ударом по самолюбию патриарха. Во время одной из проповедей в Успенском соборе он заявил о сложении патриарших обязанностей (с сохранением сана) и удалился в <a href="/wiki/%D0%9D%D0%BE%D0%B2%D0%BE%D0%B8%D0%B5%D1%80%D1%83%D1%81%D0%B0%D0%BB%D0%B8%D0%BC%D1%81%D0%BA%D0%B8%D0%B9_%D0%BC%D0%BE%D0%BD%D0%B0%D1%81%D1%82%D1%8B%D1%80%D1%8C" title="Новоиерусалимский монастырь">Новоиерусалимский Воскресенский монастырь</a>. Там Никон ждал, что царь раскается и попросит его вернуться в Москву. Однако царь поступил совсем иначе.

Царь заявил, что Никон без разрешения царя оставил церковь и отрекся от патриаршества, тем самым давая понять, кому принадлежит реальная власть в стране. Присутствовавшие церковные <a href="/wiki/%D0%98%D0%B5%D1%80%D0%B0%D1%80%D1%85" class="mw-redirect" title="Иерарх">иерархи</a> поддержали царя и осудили Никона, благословив лишение его сана патриарха и вечное заточение в монастырь. Одновременно Собор 1666—1667&#160;гг. поддержал церковную реформу и предал проклятию всех её противников, которые стали именоваться раскольниками. Участники Собора постановили передать лидеров старообрядцев в руки властей. Таким образом, реформы Никона и Собор 1666—1667&#160;гг. положили начало расколу в Русской Православной Церкви.</p>

На другой стороне царь-всадник на скачущем коне, по кругу надпись: «Божиею милостию великий государь, царь и великий князь Алексей Михайлович всея Великия и Малыя России».

Ефимок и рубль приравнивались к 64 копейкам (по весу), хотя ранее цена варьировалась от 40 до 60 копеек. Разрубленный на четыре части талер надчеканивали, таким образом появилась в обращение четвертина (полуполтинник). Была введена ещё монета <a href="/wiki/%D0%9F%D0%BE%D0%BB%D1%83%D0%B5%D1%84%D0%B8%D0%BC%D0%BE%D0%BA" class="mw-redirect" title="Полуефимок">полуефимок</a> (разрубленный пополам талер с надчеканом). «<a href="/wiki/%D0%95%D1%84%D0%B8%D0%BC%D0%BE%D0%BA" title="Ефимок">Ефимок</a> с признаком» и его доли (полуефимок и четвертина) имели хождение в основном на Украине.</p>

С этого времени Фёдор стал наследником царского престола.</p>
+<p>Со слов самого Ивана Грозного, Фёдор был «постник и молчальник, более для <a href="/wiki/%D0%9A%D0%B5%D0%BB%D1%8C%D1%8F" title="Келья">кельи</a>, нежели для власти державной рождённый».

На нём пресеклась московская линия династии <a href="/wiki/%D0%A0%D1%8E%D1%80%D0%B8%D0%BA%D0%BE%D0%B2%D0%B8%D1%87%D0%B8" title="Рюриковичи">Рюриковичей</a> (потомство <a href="/wiki/%D0%98%D0%B2%D0%B0%D0%BD_I_%D0%94%D0%B0%D0%BD%D0%B8%D0%BB%D0%BE%D0%B2%D0%B8%D1%87_%D0%9A%D0%B0%D0%BB%D0%B8%D1%82%D0%B0" title="Иван I Данилович Калита">Ивана I Калиты</a>).</p>
+<p>Большинство историков считают, что Фёдор был не способен к государственной деятельности, по некоторым данным слабый здоровьем и умом; принимал мало участия в управлении государством, находясь под опекой сперва совета вельмож, затем своего шурина <a href="/wiki/%D0%91%D0%BE%D1%80%D0%B8%D1%81_%D0%93%D0%BE%D0%B4%D1%83%D0%BD%D0%BE%D0%B2" title="Борис Годунов">Бориса Фёдоровича Годунова</a>, который с <a href="/wiki/1587_%D0%B3%D0%BE%D0%B4" title="1587 год">1587 года</a> фактически был соправителем государства, а после смерти Фёдора стал его преемником. Положение Бориса Годунова при царском дворе было столь значимо, что заморские дипломаты искали аудиенции именно у Бориса Годунова, его воля была законом. Фёдор царствовал, Борис управлял&#160;— это знали все и на Руси, и за границей.</p>

+<p><i>«Обыкновенно встаёт он около четырёх часов утра. Когда оденется и умоется, приходит к нему отец духовный с Крестом, к которому Царь прикладывается. Затем крестовый дьяк вносит в комнату икону Святого, празднуемого в тот день, перед которой Царь молится около четверти часа. Входит опять священник со святою водой, кропит ею иконы и Царя. После этого царь посылает к царице спросить, хорошо ли она почивала? И чрез несколько времени сам идет здороваться с нею в средней комнате, находящейся между его и ее покоями; отсюда идут они вместе в церковь к заутрени, продолжающейся около часу. Возвратясь из церкви, Царь садится в большой комнате, куда являются на поклон бояре, находящиеся в особенной милости. Около девяти часов Царь едет к обедне, которая продолжается два часа… После обеда и сна едет к вечерне… Каждую неделю Царь отправляется на богомолье в какой-нибудь из ближайших монастырей».</i><sup id="cite_ref-2" class="reference"><a href="#cite_note-2">[2]</a></sup></p>

+<p>Царь Фёдор Иоаннович скончался 7 января 1598 года. По свидетельству Патриарха Иова, в предсмертном томлении царь беседовал с кем-то незримым для других, именуя его великим Святителем, а в час кончины его, по преданию, ощущалось благоухание в палатах Кремлёвских. Сам Патриарх совершил таинство елеосвящения и причастил умирающего Царя Святых Христовых Таин. Феодор Иоаннович умер, не оставив потомства, и с его смертью прекратилась московская династия Рюриковичей на царском престоле в Москве. Погребен он был в Архангельском соборе Московского Кремля<sup id="cite_ref-:0_1-1" class="reference"><a href="#cite_note-:0-1">[1]</a></sup>.</p>

Что касается до других свойств его, то он прост и слабоумен, но весьма любезен и хорош в обращении, тих, милостив, не имеет склонности к войне, мало способен к делам политическим и до крайности суеверен.

+<p>Исключительно важно свидетельство неофициального, иными словами, частного исторического памятника&#160;— «Пискарёвского летописца». О царе Фёдоре сказано столько доброго, сколько не досталось никому из русских правителей. Его называют <i>«благочестивым», «милостивым», «благоверным»,</i> на страницах летописи приводится длинный список его трудов на благо Церкви. Кончина его воспринимается как настоящая катастрофа, как предвестие худших бед России: <i>«Солнце померче и преста от течения своего, и луна не даст света своего, и звезды с небеси спадоша: за многи грехи християнския преставися последнее светило, собратель и облагодатель всея Руския земли государь царь и великий князь Федор Иванович…»</i> Обращаясь к прежнему царствованию, летописец вещает с необыкновенной нежностью: <i>«А царьствовал благоверный и христолюбивый царь и великий князь Феодор Иванович… тихо и праведно, и милостивно, безметежно. И все люди в покое и в любви, и в тишине, и во благоденстве пребыша в та лета. Ни в которые лета, ни при котором царе в Руской земли, кроме великого князя Ивана Даниловича Калиты, такие тишины и благоденства не бысть, что при нем, благоверном царе и великом князе Феодоре Ивановиче всеа Русии».</i><sup id="cite_ref-:1_3-3" class="reference"><a href="#cite_note-:1-3">[3]</a></sup> Современник и близкий ко двору Государя князь И.&#160;М.&#160;Катырев-Ростовский сказал о Государе так:</p>
+<blockquote>
+<p><i>«Благоюродив бысть от чрева матери своея и ни о чем попечения имея, токмо о душевном спасении». По его свидетельству, в Царе Феодоре «мнишество бысть с царствием сплетено без раздвоения и одно служило украшением другому».</i><sup id="cite_ref-:0_1-2" class="reference"><a href="#cite_note-:0-1">[1]</a></sup></p>

+<p><i>«Царь Феодор Иоаннович был удивительный, светлый человек. Это был воистину святой на троне. Он постоянно пребывал в богомыслии и молитве, был добр ко всем, жизнью для него была церковная служба, и Господь не омрачил годы его царствования нестроениями и смутой. Они начались после его смерти. Редко какого царя так любил и жалел русский народ. Его почитали за блаженного и юродивого, называли „освятованным царем“. Недаром вскоре после кончины он был занесён в святцы местночтимых московских святых. Народ видел в нем мудрость, которая исходит от чистого сердца и которой так богаты „нищие духом“. Именно таким изобразил царя Федора в своей трагедии Алексей Константинович Толстой. Но для чужого взгляда этот государь был другим. Иностранные путешественники, соглядатаи и дипломаты (такие как Пирсон, Флетчер или швед Петрей де Эрлезунда), оставившие свои записки о России, в лучшем случае называют его „тихим идиотом“. А поляк Лев Сапега утверждал, что „напрасно говорят, что у этого государя мало рассудка, я убежден, что он вовсе лишен его“».</i><sup id="cite_ref-4" class="reference"><a href="#cite_note-4">[4]</a></sup></p>
